Or, from the management system, use the snmpwwalk command to identify the interface index. show interface EXEC Privilege Enter the command snmpset to change the admin status using either the object descriptor or the OID. Choose integer 1 to change the admin status to Up, or 2 to change the admin status to Down. snmpset with descriptor: snmpset -v version -c community agent-ip ifAdminStatus.ifindex i {1 | 2} snmpset with OID: snmpset -v version -c community agent-ip .1.3.6.1.2.1.2.2.1.7.ifindex i {1 | 2} Fetch Dynamic MAC Entries using SNMP Table 38-6. MIB Objects for Fetching Dynamic MAC Entries in the Forwarding Database MIB Object dot1dTpFdbTable dot1qTpFdbTable dot3aCurAggFdbTable OID .1.3.6.1.2.1.17.4.3 .1.3.6.1.2.1.17.7.1.2.2 .1.3.6.1.4.1.6027.3.2.1.1.5 Description List the learned unicast MAC addresses on the default VLAN. List the learned unicast MAC addresses on non-default VLANs. List the learned MAC addresses of aggregated links (LAG). MIB Q-BRIDGE MIB F10-LINK-AGGREGATION-MIB In Figure 38-22, R1 has one dynamic MAC address, learned off of port GigabitEthernet 1/21, which a member of the default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress, dot1dTpFdbPort, and dot1dTpFdbStatus. Each object is comprised an OID concatenated with an instance number. In the case of these objects, the instance number is the decimal equivalent of the MAC address; derive the instance number by converting each hex pair to its decimal equivalent. For example, the decimal equivalent of E8 is 232, and so the instance number for MAC address 00:01:e8:06:95:ac is .0.1.232.6.149.172. The value of dot1dTpFdbPort is the port number of the port off which the system learns the MAC address. In this case, of GigabitEthernet 1/21, the manager returns the integer 118. The maximum line card port density on the E-Series is 96 ports, and line card numbering begins with 0; GigabitEthernet 1/21 is the 21st port on Line Card 1, and 96 + 21 yields 118. 696 | Simple Network Management Protocol
