Overview

Retreive SECY MIB data for MACsec interfaces by using SNMP commands.

Retrieve SECY MIB information from a device using SNMP commands.

You need to query SECY MIB data for MACsec interfaces on a device with SNMP enabled.

Before you begin

Ensure you have the correct SNMP community string, management IP address, and interface ifIndex.

Follow these steps to retrieve SECY MIB data:

Procedure

1.

Walk the entire SECY MIB subtree to enumerate all objects.

Example:

snmpwalk -v2c -c <community_string> <management_IP> 1.0.8802.1.1.3
2.

Query the TxSCI value for a specific interface using its ifIndex:

Example:

snmpget -v2c -c <community_string> <management_IP> iso.0.8802.1.1.3.1.1.2.1.1.<ifIndex>
3.

Find the ifIndex of the MACsec controlled port by performing an SNMP walk on the IfMib:

Example:

snmpwalk -v2c -c <community_string> <management_IP> 1.3.6.1.2.1.31.1.1.1.1
4.

Alternatively, use the show snmp interface command to display SNMP interface information:

You will obtain SECY MIB data and the interface index needed for targeted SNMP queries.
