Hello - I need help to get a script for Deploying Static EPG in VPC interface. The equivalent CLI configuration is below vpc context leaf 2471 2481 interface vpc VPC-TO-APPSERVER switchport trunk allowed vlan 200 tenant PROD application AP_SERVER epg EPG_DMZ_VLAN200_SERVER switchport trunk allowed vlan 201 tenant PROD application AP_SERVER epg EPG_DMZ_VLAN201_SERVER exit This is my learning, but I am not able to get the right script for deploying the EPG in VPC. I have around 200 lines of CLI commands to achieve this. 1) I tried to download the xml file (configuration only) in the path Tenant--> PROD--> Application Profiles-->AP_SERVER->EPG_DMZ_VLAN200_SERVER. The output has only a line of XML header. 2) arya.py -f <filename>.xml -i 10.100.206.1 -u <credentials> to get the cobra scripts regards,Sairam

:). I started this discussion because, recently i upgraded my Internet bandwidth from 10 Mbps to 100 Mbps in 2911 Router and if the WAN bandwidth exceeds ( the sum of Transmit and receive) 50 Mbps, we saw a lot of packet drop When you say even the LAN facing interface should not exceed throughput specification (for example 35 Mbps for 2911) it is worrying factor for buyers.

Thanks again - When you say 4221 can support up to 75 Mbps ( with Performance License), what is the purpose of 1000 Mbps on-board LAN port in that Router. Can't the Router handle more than 75 Mbps traffic from the LAN switch to this Router? I am convinced WAN cannot exceed 75 Mbps, but how about LAN side traffic (with no WAN protocols)

snarayanaraju · ‎03-11-2019

Thanks Leo for responding. Please read below. Can i understand this way by reading the product specification sheet. Question 1) Because the Throughput (in Mbps) of 4221 is 35 Mbps, the maximum WAN link should not exceed 35 Mbps to get optimal performance? If i have 2 WAN links connected to the same Router (MPLS and Internet) the sum traffic passing thru on the both the Links (Transmit and Receive) should not exceed 35 Mbps at any point of time ? Question 2) Should i consider the speed or Traffic on the Interface that connects to LAN. Example can i connect 1000 Mbps link from LAN switch to this Router though the Throughput mentioned is 35Mbps? Datasheet of 4000 ISR: https://www.cisco.com/c/en/us/products/collateral/routers/4000-series-integrated-services-routers-isr/data_sheet-c78-732542.html regards,Sairam

Hello - It is a general question to know how to determine the model of the Router based on the WAN Internet link i am going to connect. Reading the article http://www.anticisco.ru/pubs/ISR_G2_Perfomance.pdf and other datasheet it is mentioned about the "Throughput" of the Router. This throughput is the forwarding capacity of the backplane of the Router? If the Interface of the Router is supported 1 Gbps why any Router cannot have the WAN link maximum to 1Gbps? For example, i have 2911 Router having 10Mbps Link, We are going to upgrade the link to 200Mbps. Want to know if this router supports this WAN link. I have different category of traffic like Voice, Data, QoS, BGP on Internet link Can you help me please regards,Sairam

Thanks all for sharing ideas, expertise solutions and answer. I need a help We are planning to migrate Point to Point GRE tunnels to DMVPN or MGRE tunnels where Datacenter(Hub) router will have one tunnel and remote sites will have GRE tunnel to my Hub Router. I current situation we have the flexibility of shutting down a GRE Tunnel of a remote site (Example: Chicago Office) from Hub itself by getting into the respective tunnel of Chicago and give command "shutdown" and later by "no shutdown" I can bring up the site. This requirement arises during troubleshooting What is the way I can shutdown a remote office Tunnel from Hub Router if I migrate to DMVPN or mGRE tunnel? regards,Sairam

Hello Leonardo - How are you.

Thanks Rasika - It helps. By the way thanks for your posts on https://mrncciew.com/ :)

snarayanaraju · ‎12-06-2018

Thanks Rasika - I was worrying about what will happen if 120 number of APs with inferior code start getting associated to the higher version of WLC (Secondary in our case). Will all the 120 APs will be pushed to the new Code from the WLC simultaneously ? thanks,Sairam

snarayanaraju · ‎12-06-2018

Hello - We have two 5508 WLC. 120 Wireless accesspoints (AP) all associated to Primary WLC. Recently a Secondary WLC has been upgraded to latest code whereas Primary is still with old code itself. The objective is to move all these 120 APs to Secondary WLC. Method 1: Moving each APs manually by changing the Primary and Secondary Controller IP address settings in the APs. But it is a time consuming job Method 2: Shutting down Primary WLC so that all the APs will start associating with Secondary WLC. The question is, if i follow Method 2, will it be a overhead for Secondary WLC as it has to push code to all these 120 APs simultaneously? Will this approach is advisable? Will it be a good idea for smooth migration? Thanks in advance, SAIRAM

Thanks, It makes sense. However the diagram is attached for your reference

snarayanaraju · ‎12-04-2018

Thanks again. I understand the resilenccy you refer. Specific to the topology i refer in the attached diagram What is the disadvantage i will have if I don't have iBGP between these WAN routers

snarayanaraju · ‎12-04-2018

Thanks Paul - What is the advantage of using iBGP between the WAN Routers as each prefixes i learn from eBGP is getting redistributed EIGRP and my Core switch is going to decide what is the next Hop.

snarayanaraju · ‎12-04-2018

Hello All - Refer the diagram attached. What is the advantage or requirement of configuring iBGP session between Router 1 and Router 2. learning prefix 10.1.0.0/16 in R1 using eBGP between R1 and R3 learning prefix 10.1.0.0/16 in R2 using eBGP between R4 and R2 Using network command in R1 and R2, advertising 192.168.1.0/24 to R3 & R4 respectively EIGRP between R1 and LAN L3 Switch. Redistribute BGP to EIGRP EIGRP between R2 and LAN L3 Switch. Redistribute BGP to EIGRP regards,SAIRAM
