www.dell.com | support.dell.com Enabling and Disabling a Port using SNMP Step 1 2 3 Task Command Syntax Command Mode Create an SNMP community on the Dell Networking system. From the Dell Networking system, identify the interface index of the port for which you want to change the admin status. Or, from the management system, use the snmpwwalk command to identify the interface index. snmp-server community show interface CONFIGURATION 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} Fetching Dynamic MAC Entries using SNMP Dell Networking supports the RFC 1493 dot1d table for the default VLAN and the dot1q table for all other VLANs. Note: The 802.1q Q-BRIDGE MIB defines VLANs with regard to 802.1d, as 802.1d itself does not define them. As a switchport must belong a VLAN (the default VLAN or a configured VLAN), all MAC address learned on a switchport are associated with a VLAN. For this reason, the Q-Bridge MIB is used for MAC address query. Moreover, specific to MAC address query, dot1dTpFdbTable is indexed by MAC address only for a single forwarding database, while dot1qTpFdbTable has two indices -VLAN ID and MAC address -to allow for multiple forwarding databases and considering that the same MAC address is learned on multiple VLANs. The VLAN ID is added as the first index so that MAC addresses can be read by VLAN, sorted lexicographically. The MAC address is are part of the OID instance, so in this case, lexicographic order is according to the most significant octet. Table 46-6. MIB Objects for Fetching Dynamic MAC Entries in the Forwarding Database MIB Object OID Description dot1dTpFdbTable .1.3.6.1.2.1.17.4.3 List the learned unicast MAC addresses on the default VLAN. dot1qTpFdbTable .1.3.6.1.2.1.17.7.1.2. List the learned unicast MAC addresses on 2 non-default VLANs. dot3aCurAggFdb .1.3.6.1.4.1.6027.3.2. List the learned MAC addresses of aggregated Table 1.1.5 links (LAG). MIB Q-BRIDGE MIB F10-LINK-AGGREGATION -MIB In Figure 46-23, R1 has one dynamic MAC address, learned off of port TenGigabitEthernet 1/21, which a member of the default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress, dot1dTpFdbPort, and dot1dTpFdbStatus. 852 | Simple Network Management Protocol (SNMP)
