Been working in Networking for last 10 years, a mixture of jobs on implementation, design, support across most of the Cisco product range, alongside other vendors!
Currently working for CSC (Computer Science Corporation) as a Network Support Engineer in the datacentre arena.
Involved in the first UK deployment of UCS within CSC.
I hope this is a relatively easy question to answer.
I have some Nexus 7010's that I need to monitor via SNMP. Currently, we can poll the switch and get some info back, however we only see physical interfaces that belong to the Admin VDC.
In order to be able to poll interfaces within a non-Admin VDC, do I have to configure SNMP communities (and an IP to respond to the poll) within each VDC ? Or is there a way to poll them from the Admin VDC?
bash-2.05$ snmpwalk -v 2c -c public <ipaddr-in-admin-vdc> .184.108.40.206.220.127.116.11.1.1.1
IF-MIB::ifName.83886080 = STRING: mgmt0

Hi all, I have an issue with a couple of ASR's and retrieving certain SNMP interface statistics. I can collect values from one sub-interface, but not another. Correct retrieval of statistics (increments as expected) bash-2.05$ snmpwalk -v 2c -c <community> <router_ip> .18.104.22.168.22.214.171.124.126.96.36.199 IF-MIB::ifName.29 = STRING: Gi0/0/0.2
bash-2.05$ snmpwalk -v 2c -c <community> <router_ip> .188.8.131.52.184.108.40.206.220.127.116.11 IF-MIB::ifHCInOctets.29 = Counter64: 195098251378
Not retreiving correct volume (stays constant) bash-2.05$ snmpwalk -v 2c -c <community> <router_ip> .18.104.22.168.22.214.171.124.126.96.36.199
IF-MIB::ifName.37 = STRING: Gi0/0/0.1 bash-2.05$ snmpwalk -v 2c -c <community> <router_ip> .188.8.131.52.184.108.40.206.220.127.116.11
IF-MIB::ifHCInOctets.37 = Counter64: 12660 bash-2.05$
I have verified that I'm walking the correct ifIndex: router#sh if-mgr db interface ifName ifName ifIndex

Hi all, One of our ACE-20's crash recently with little info as to why - fortunately it was the FT standby module so service wasn't impacted but obviously keen to determine the cause of the crash, and potential resolution. Running A2 (3.5). last boot reason: NP 1 Failed : NP Core Reset - Cause Unknown There is nothing obvious from the switch perspective: Apr 17 14:52:35.775 bst: SP: The PC in slot 9 is shutting down.

Hi all, Just getting my feet wet with UCS and have our first system basically setup. However I have defined 2 NTP servers within UCSM but it doesn't appear to be working. I've been hunting for an equivalent to show ntp status from IOS but so far haven't found one. Is there a way to check the time sync status? Or would errors be captured in a log anywhere? Thanks, Anthony
