Hi,
All the other switches / routers on quering for SNMP sysName.0 returns their FQDN in our network. The Nexus 7010 and 5020 switches in the network return only their name. "hostname xx" and "ip domain-name xx" defined on all the devices. The SNMP MIB is matching. There are no other SNMP related issues. How can I get the FQDN for these devices ?
$ snmpget -v 2c -c public m-65k-00.core sysName.0
SNMPv2-MIB::sysName.0 = STRING: m-65k-00.core.abcd.com
$ snmpget -v 2c -c public m-N7K-00.core sysName.0
SNMPv2-MIB::sysName.0 = STRING: m-N7K-00
$ snmpget -v 2c -c public m-N7K-00.core.abcd.com sysName.0
SNMPv2-MIB::sysName.0 = STRING: m-N7K-00
Thanks,
Rashid.
Solved! Go to Solution.

Hi Rashid,
Forgot to mention something, this object is context-aware, if for example your SNMP requests arrive on the mgmt0 interface it's necessary to configure the domain-name under the VRF not just globally, eg:
vrf context management
ip domain-name lab.cisco.com
I checked the versions you mentioned in my lab and see the expected behaviour (sysName contains FQDN) when the above config is in place.
Kind Regards,
/Phil

Thanks Phil, That was really helpful. Seems the problem might not be fixed in (or re-appeared) in later releases. We are facing the issue both in N7K and N5K. They N7K in particular is running a later version than the earlier fixed version according to the bug page.

Hi Phillip,
That did the trick. Its working returing FQDN now.
Thanks for your time.
