Have you looked at the Network Router / Switch Wizard?

[raamardhani7]

Network Router / Switch Wizard is giving port number and bandwidth.But is not giving the port description e.g port 10124 is for FKR-VPN-ASA or port 10624 is for ATT MPLS.This details we can get if we some how use Network Router / Switch Wizard with OID 1.3.6.1.2.1.31.1.1.1.18.This details I am getting using the SNMPWALK plugin but for many device am not getting entire port on the device so cant use that.

1.3.6.1.2.1.31.1.1.1.18 is IF-MIB::ifAlias, not IF-MIB::ifName which is the one the wizard queries.

You can also use the SNMP Walk wizard which will by default go through all IF-MIB and allow you to select the appropriate OID's.

Or you can create your own custom wizard/plugin to do this.

The wizard uses the /usr/local/nagios/libexec/check_rrdtraf plugin so you can also modify that if need. Just be aware this would get overwritten on a upgrade.
