[c-nsp] SNMP and port channel IOS

[John Payne]

Is anyone monitoring port channels with SNMP?  Things like which  
physical interfaces are in which port channel?  Against a switch with  
2 interfaces in a portchannel:

snmpwalk -v 2c -c public 192.168.11.13 .1.3.6.1.4.1.9.9.285
enterprises.9.9.285 = No Such Object available on this agent

(from the CISCO-PORT-CHANNEL-MIB file).

I haven't found anything related that would help... so any hints  
would be much appreciated!
