Overview

Provides practical examples of SNMP commands, such as snmpwalk and snmpget, that enable network administrators to retrieve and monitor SECY MIB data for MACsec-enabled interfaces.

The following commands enable network administrators to access and query SECY MIB data from a router using SNMP. These examples assume the SNMP community string is set to public and the device management IP address is 10.0.0.1.

Obtaining the MACsec Controlled Port Interface Index

To perform an SNMP walk on the entire SECY MIB:

snmpwalk -v2c -c public 10.0.0.1 1.0.8802.1.1.3

To query the secyTxSCTable and obtain the TxSCI value for interface Gi0/1/0/0 (where the ifindex for MACsecControlled0/1/0/0 is 18):
```
snmpget -v2c -c public 10.0.0.1 iso.0.8802.1.1.3.1.1.2.1.1.18
```

These SNMP query examples help administrators retrieve security-related MIB data for monitoring and management of router interfaces.
