AltostratusF5 LTM and What's Up Gold
Hello,
I recently implemented 2, big ip 1600 ltm devices configured as a redundant pair. everything is working great so far.
I have enabled snmp on the standby ltm, however I can't get our What's Up Gold server to see the snmp agent or even try to browse the ltm using mib walker.
If I execute the following query on the standby node I get the following output:
[root@sna9lt1600n2:Standby] / snmpget -c FATFSB 10.244.248.18 sysGlobalStat.sysStatMemoryUsed.0
F5-BIGIP-SYSTEM-MIB::sysStatMemoryUsed.0 = Counter64: 43446672
This confirms the agent is working, right?
Anyhow, any help is greatly appreciated.
Thanks,

yes the agent is working if you are getting a response locally. Have you added your what's up gold server's IP address to the SNMP Access field in System->SNMP->Agent->Configuration ? 
rpalacios_79340Yes.
Does it matter if (loop address) 127. is on top of the IP of my wug server?- JRahmOK, no the order shouldn't matter. Do you have the routes necessary to return traffic to your server? Any firewalls in between that would block snmp traffic?
- rpalacios_79340No firewalls. If you are refering to the routes configured for the manament IP, there is one specified. I can ping my WUG server using hostname and IP from the standby host. I can also ping the standby device from the wug server.
I have also restarted the snmpd service on the standby device with no luck. I've also installed the MIBs on the WUG server with no issues. - dennypayne

The traffic may not necessarily be trying to go out the management port, it may be trying to use the LTM's default gateway, unless you've put a specific management route to the WUG server's IP. (b mgmt route x.x.x.x netmask y.y.y.y gateway z.z.z.z is the syntax I think).
Denny - JRahmGet a tcpdump capture on the management interface and the interface with your TMM default gateway and see if the requests are arriving on your LTM mgmt interface, and where, if any, they are being returned. If the LTM is receiving the requests and not responding, and you've ensured the host IP is allowed, I'd get a case open with support.
- rpalacios_79340Well guys...I came in this morning and it was working. Don't know what happened.
Anyhow, thanks everyone for your assistance.
