Dear All,
I'm facing problem with my 2nd Cisco 3750, its about SNMP, for sure i can get responce with:
snmpwalk -v 2c -c SWDC1 202.188.5.2 IP-MIB::ipAdEntIfIndex
Result:
IP-MIB::ipAdEntIfIndex.202.188.5.2 = INTEGER: 1
But when i try to:
snmpwalk -v 2c -c SWDC2 202.188.5.3 IP-MIB::ipAdEntIfIndex
I will get result with:
Timeout: No Response from 202.188.5.3
May i know what the problem is ?
Please help and Thank you so much
P/S: Attach with diagram.

Hi,
Can you confirm that you have IP connectivity to SWDC2 from your NMS i.e., if you run ping 202.188.5.3 from your management system that you get a successful response.
If that's confirmed you should check that the community string you're using is the same as that configured on the switch. On the switch execute the show running | in ^snmp-server community command and ensure the string seen is the same as you're using.
Additionally check to see whether the snmp-server community <string> command in your configuration uses an access list e.g., snmp-server community SWDC2 RO 10. If it does, then ensure the IP address of your NMS is included within the ACL.
Note that the snmp-server community command may also be configured with the RW (Read-Write) string and use a named access list rather than a number.
Regards
