Hello, Thanks in advance for anyone who can help to clarify the situtation my customer has for Nexus 1010. One of our customer bought a pair of Nexus 1010 physical appliance. One thing strange is that both Nexus 1010 do not come with 1 x Quadport GE NIC Card. All Cisco Nexus 1010 doc says the Nexus 1010 has 2 Ethernet port (port 1 and port 2) built on mother board, and a Quadport GE NIC Card installed (port 3-6). Cisco dynamic configuration tool for Nexus 1010 does not have the option of choosing this Quadport GE NIC Card. I am wondering why the Nexus 1010 did not have the extra card installed. Thanks for your assistance! Fuming

Aniks, Thanks very much for your quick response!!! As I know, Nexus 1010 is built on top of C-Series Rack server. Below is my understanding: 1) CIMC is the out-of-band management port for remote management/access to Nexus 1010. Explanation: a) CIMC on Nexus 1010 is a Physical RJ-45 Port (10/100Mb) used for Out-of-Band management for access to the Nexus 1010 console (Searial-Over-LAN). b) The two Nexus1010 in the HA pair can have different IP addresses for CIMC port. c) CIMC can be used for initial setup of Nexus 1010. 2) management 0 is in-band: this IP address can be accessed from the network. a) The management 0 IP address/management VLAN -->tagged port Ethernet 1 and 2 to your uplink switches b) All VSB (VSM) inherit this management VLAN. So, the IP addresses of CIMC port and management 0 are different, they can not talk? Please correct me if I am wrong, Thanks in Advance!!!

Nexus 1000v/1010 experts: Can someone clarify the difference between Nexus 1010 CIMC interface and management 0 interface? I read lots of cisco docs about Nexus 1000v and Nexus 1010, but have not get my hands on physically. 1) You can assign IP address to CIMC port (10/100Mb) when installing Nexus 1010, in HA pair, primary and secondary can have different CIMC addresses, right? From the remote management configuration: Configuring Remote Management: SUMMARY STEPS 1. config t 2. nexus1010-system remote-mgmt primary ip ipaddr username username password password 3. nexus1010-system remote-mgmt secondary ip ipaddr username username password password When you install Nexus 1010 without CIMC (through console), you configure a management 0 (management VLAN) IP addresses, Question: 1) CIMC is used for Serial-over-LAN (connecting to CIMC ports, then "connect host"-->Nexus 1010 console? So, is the management 0 IP address (shared among HA pair) different from CIMC port addresses (two Nexus 1010 can have different CIMC addresses)? Thanks in advance

Hello Cisco Data Center Solution/Architect experts: As a cisco partner, we recently submitted a RFP(request for proposal) for one of our data center customers to upgrade their data center infra-structure and design/solutions. After 1st round of bid, it comes down to two competitors: us (cisco partner) and another competitor (HP partner) Now it comes down to the final round to determine who will win thye bid! I am posting this to ask for some documents comparing Cisco data center products/solution vs HP products/solution. I am familiar with Cisco products and solutions but know little about HP. So any documents show benefits of choosing cisco would be very helpful!!! 1) Comparison of Cisco data center switch platforms (mainly Nexus family vs HP switches) 2) Cisco has end-to-end solution, while HP does not? 2) Why Cisco solution? Greatly appreciate any suggestions and replies.

Hi Rob, You need to re-seat the SUP in question (redundant SUP in your case): loose the screws completely on both sides of the Supervisor engine, then slide out the supervisor blade, slide in/reseat the supervisor engine blade properly. Using show commands to verify: show module all One thing to note: "show logging" and "show logging system" tell you different stories. You may find that the message you had only appear when you type "show logging system" but not in "show logging". Basically it tells you that the Chassis/IOS is testing the sup in question. I believe that if you reseat the sup in question, this isssue will be resolved. Please let me know if this helps. Fuming

Milan, Thanks! In your case, the total memory used by BGP is less than 1MB (3,000 prefix). I believe that even with big ISP, say Cogent, their directly connected customer prefix less than 40,000. Counting two ISPs, the prefix number will rise. 256Mb memory on 2821 might be enough. Although It may experience high CPU usage during bgp updates or neighbor establishment. thanks again, Fuming

Hi all, I have a question about ISR2821 as a BGP router. Here is the info, We have a customer currently having one ISP (20MB) with ISR2821 as edge router running BGP accepting only default route from current ISP. They will soon bring up another 100MB link from 2nd ISP. To better utilize both links, I want to do load sharing using BGP attributes (local preference and as-path prepend). To realize this, I want ISP to advertise their directly connected customers (partial routes) plus a default route. The question is "can ISR2821 handle this", will 2821 have high CPU utilization and memory issue? As default, 2821 has 256MB memory. Anyone had experience in a similar situation? Thanks!!! PS: I am considering ISR G2 for the 2nd BGP router, ASR 1000 series may be a budget issue.

Hi, You missed the following on ASA: crypto map TELEFIN_LAN_map 1 ipsec-isakmp #### phase 2 SA policy not acceptable! (local 1.1.1.1 remote 2.2.2.2) ######## The dedug message essentially says: phase 2 SA policy not matching, and was not acceptable. After making changes, remove and re-apply crypto map.

Jon: Great discussion and advice! I know PBR on core switches and Static on ASR edge router (may also need static on ASA) would work, and I hate to configure a list of static routes/PBR, and do redistribution. Also this may add complications of next-step network deployment. Another ASR1002 will be added as edge router and each ASR will be EBGP peering with a ISP. The reason "I came up with this dynamic failover" was that customer has some curiosity that if both ASA (actually two FWSM) can be active. So I came up with this proposal and want to verify it. To deploy/migrate in production network, cautiousness is always a good thing, and sometimes an odd idea may not work but it improves understanding, although I know that active/standby failover is a cisco proven solution, and the throughput of FWSM or ASA is enough for internet traffic (bottle neck of the internet link). Thanks again for the discussion and advice.
