A. The Catalyst 6800 Series does not replace the Catalyst 6500 Series. There is not an end-of-life (EoL) plan for the Catalyst 6500 Enhanced (6500-E) Series platform. The focus of the Catalyst 6800 Series is to bring your backbone experience to the next level. All of the new line cards still work with the Catalyst 6500-E Series in order to provide investment protection.
A. In a Catalyst 6800 Series switch, the per-slot switching capacity is much higher than in the Catalyst 6500-E Series chassis. The Catalyst 6500-E with Supervisor Engine 2T (Sup2T) can do a maximum of 80 G per slot. The same Sup2T on the Catalyst 6807-XL can do 220 Gb/s per slot and the maximum the Catalyst 6807-XL can do is 880 Gb/s per slot with Active Supervisor. The Catalyst 6807-XL has new power supplies which are platinum efficient. It also has a more efficient redundant fan tray than the Catalyst 6500.
In order to understand more about Catalyst 6800 Series switches, see Cisco Catalyst 6807-XL - Innovation with Investment Protection for Tomorrow’s Campus Backbone.
A. The new Catalyst 6807-XL switch supports the current service modules: Network Analysis Module 3 (NAM3), Wireless Services Module 2 (WiSM2), Adaptive Security Appliance Security Module (ASA SM), and so on.
A. Macsec is supported on all SFP+ based 10G ports in hardware.
A. The airflow is right to left, similar to the Catalyst 6500-E chassis.
A. To be determined. The chassis can provide additional fabric channels with the intent to support up to 4 x 40 G or 2 x 100 G ports per slot.
A. The focus of the Cisco Catalyst 6800 Series is to bring your backbone experience to the next level and the enterprise environment. The Nexus 7000 and Nexus 5000 are datacenter-oriented.
A. No, there is not support for Sup720 on the Catalyst 6807-XL chassis. Only Sup2T is supported.
A. No. Supervisor slots are supported for use only by Subversion or Service Modules; no line cards are supported.
A. Yes, it is a single supervisor and fixed.
A. Yes. It supports LISP and NAT, as well as the PAT feature.
A. FWSM is not supported on the Catalyst 6807-XL. ASA SM is the only SM supported. The same SMs are supported on the
6807-XL chassis as those that Sup2T supports on the Catalyst 6500-E.
A. Today it only supports Sup2T. All of the Sup2T features are supported.
A. The Catalyst 6800 Series targets a campus implementation, not a datacenter implementation. On the OTV side, Cisco supports Virtual Private LAN Service (VPLS)/Advanced VPLS (A-VPLS) and Layer 2 over Generic Routing Encapsulation (L2oGRE), so there is an alternative option on this platform.
A. An adaptor will be used to convert 4 x 10 G into a 40 G.
A. Yes, it does support DWDM-Transceiver.
A. Nexus is for datacenters and Catalyst is for a campus environment. The Instant Access (IA) solution on Catalyst is not meant for ToR deployment, even though it can do that. The target is campus access as it supports Power over Ethernet (PoE), stacking, and so on.
A. Future supervisors will also be supported, but they cannot work more than 92 G per slot switching throughput.
A. The current switches do not support a redundant power supply. They only support one power supply with redundant power.
A. The Catalyst 6807-XL had switching modules, but they are not on the Catalyst 6880-X.
A. See these two documents:
A. This is just a testing limitation. We are planning to raise this limit to 2,000 ports (42 IA switches) by the end of the year.
A. Yes, you will see more toward the end of 2014. The Catalyst 6807-XL supports 40 G with the 6904 module.
A. It supports up to 1 million IPv4 addresses, 512,000 IPv6 addresses, and 128,000 MAC addresses.
A. Yes, there will be one PK and OpenFlow 1.3 client in Q4CY14. Cisco currently runs a POC with selected customers and can provide an image if it is needed.
A. No. There are only images for Sup2T. This is mainly because Cisco can leverage the new PFC4 functionality for matching and the bigger netflow table can be leveraged for OpenFlow. There are no plans to do this for Sup720.
A. Yes, you can connect 29XX and 3XXX switches in the Traditional manner. These do not support Instant Access with the current release.
A. There are a total of nine fans in the Catalyst 6807-XL. Three can fail and you have 120 seconds to remove the faulty fan tray and insert the new one.
A. It is an adapter that takes four ports of SFP+ and provides a QSFP input where you can connect any ordinary 40 G optics.
A. There will be a next generation line card. The code is mature, so the only limitation might be the scale for day one. However, it is really up to you to see if that is a limitation for your deployment.
A. Nexus has its own implementation of VSS which is called Virtual Port Channel (vPC). It has two different boxes which are managed separately so there are two control plans, but both these plans are in sync with each other. Catalyst switches do not have two control plans. Currently only one control plan is active and is used to manage the data plan for both devices. There are two different implementation methods; one method is used for a datacenter and the other method is used for an enterprise implementation. The VSS is more suitable for an enterprise implementation in terms of a single point of management, simplicity, and feature richness. In a Fabric Extender (FEX) solution, the Catalyst 6800IA (Instant Access) works with the Nexus 6000 solution of VSS and these are not interoperable.
A. Typically in an enterprise space, live closets are small and the access to the unit from the back is not possible. Therefore, access from the front of the unit is the only choice. Site-to-site airflow is only the way to cool the unit. This is an enterprise solution and is customized for enterprise space.
A. No, the Catalyst 6800 does not support VDC functionality.
A. No, the current version of software only allows it to run one control plan at a time. When you club two switches with VSS technology, the control plan of the active supervisor processor and the data plan of both supervisors are used for operation.
A. No, it does not support FCoE. FCoE is generally used in datacenter devices such as the Nexus 7000, 5000, and so on. The Catalyst 6800 is more of an enterprise device and it does not concentrate on data technologies.
A. No, it is not supported today.
A. First, there are no plans to end-of-sale (EoS) the Catalyst 6500-E Series. VSS works exactly the same on the Catalyst 6800 and the Catalyst 6500-E since both are powered by the same Sup2T and the same Cisco IOS®. The Catalyst 6000 Series does not support vPCs since this is a Nexus feature.
A. If you use the In-Service Software Upgrade (ISSU) and the ESS mechanism there should not be any downtime. The same supervisor and Cisco IOS are used by the Catalyst 6500-E Series and the Catalyst 6807-XL chassis. Hence, there is no difference in operations.
A. It takes 50 to 200 ms of convergence time for Quad VSS.
A. Yes, it supports VSS.
A. No, such an implementation is not supported.
A. The line card and ports stay up and there is a maximum 200 ms traffic disruption.
A. With Quad Sup there is only one supervisor which is active from the control plane perspective. All supervisors are active from the data plane. The advantage you receive with Quad Sup is that when there is a failure of one supervisor in each chassis there is no impact. The standby supervisor within that chassis takes over and convergence is less than 200 ms.
A. Yes, the Catalyst 6500 supports Quad Sup VSS.
A. No, there are no plans to bring Quad Sup VSS to the 4000.
A. Quad Sup is supported only on the 6500. It is not supported on the 4500.
A. All line cards with Sup2T are supported in VSS.
A. No, this is not supported. You need the same model.
A. Both switches become active. This is called dual active, and there are techniques to detect this such as EPAGP, Fast Hellos, and BFD. Once it is detected, the active supervisor or switch moves into recovery mode and shuts down all ports except the VSL interfaces.
A. It is the feature with nonstop forwarding (NSF). Neighborship never goes down; it is just reestablished.
A. ISSU is an in-service software upgrade and ESSU is enhanced service software upgrade. ISSU is essentially replicated and the software upgrade happens hitless. ESSU is an enhanced form of that.
A. In the NX-OS run on vPC, two control plans and data plans are both active. In Catalyst 6000, VSS runs with Cisco IOS. A single control plan is active at a time and controls both data plans across the chassis and provides a single point of management, simplicity, and feature richness. Additionally, the Catalyst 6800 VSS allows you to have Quad Sup redundancy in order to provide hyper-high availability.
A. Yes, the Catalyst 6800IA switch is like a fabric extender.
A. It is a similar concept from the management perspective (single point of management). However, the Catalyst 6800IA is targeted for a campus environment. It supports PoE+, stacking, and a downstream switch connection. Also, the optics supported to connect the Catalyst 6800IA are ordinary optics.
A. Not on the line cards. Cisco provides PoE with the Catalyst 6800IA.
A. Today they only support 10G.
A. Yes. It will increase up to 5 stacks.
A. It is like a FEX with campus-specific features: PoE, stacking, and compact switch connection.
A. Yes, you can have trunk ports on an IA switch.
A. Yes, it retains the configuration.
A. No local switching performs on the IA. All switching decisions happen on the parent. Since you can stack up to three switches, and each switch has two 10 G ports, there is a total of 60 G uplink.
A. You need to connect those switches to another VSS Cluster. The current software only supports 1008 ports per VSS cluster.
A. The Catalyst 6880 will natively support IA with the next release.
A. Yes, STP is disabled on the links between the parent and the IA client.
A. IA is supported on the Catalyst 6807-XL as of today, but support on the Catalyst 6880 will come in the March 2014 release.
A. It is the same as the Catalyst 6807-XL; 1008 ports, 21 IA switches, and three per stack. If not stacked, then 12 standalone switches.
A. No, you cannot swap IA and Nexus 2000.
A. No, there is no FET support on IA.
A. Yes, it is supported.
A. It supports 15 watts on all 48 ports and 30 watts on 24 ports.
A. The Catalyst 6800 supports up to 1,000 access ports today.
A. The IA client and parent communicate over four control protocols: Satellite Discovery Protocol (SDP), Satellite Registration Protocol (SRP), Satellite Configuration Protocol (SCP), and Inter Card Communication (ICC). These are at the heart of the IA.
See the Cisco Catalyst Instant Access Solution for more information.
A. On each IA client you can have 48 PoE ports or a maximum of 24 PoE+ ports.
A. There is no such plan. It will remain with the Catalyst 6000 Series (6500/6800) as a parent.
A. Support for IA starts with Cisco IOS Software Release 15.1(2) SY.
A. No, there are no plans today to support UPoE on the Catalyst 6800IA.
A. No. The configuration is completed on the IA unit. All of the configurations are on the parent.
A. No, there is no local switching.
A. This depends on the performance you require. The minimum recommended is two, but you can go up to six ports of 10 G.
A. Yes, it requires a reboot. It is like a line card in a Catalyst 6000 Series chassis, but you can stagger the reboot. You have the option to upgrade the IA along with the parent or you can upgrade the IA at a later stage. As part of the IA upgrade process the IA is rebooted. If there is stack of three switches, all three are rebooted.
A. In Cisco IOS Software Release 15.1(2) SY, there are 21 IAs and 12 FEX-IDs. It can stack up to three switches.
