11 Layer 2 The Aggregator supports CLI commands to manage the MAC address table: • Clearing the MAC Address Entries • Displaying the MAC Address Table The Aggregator auto-configures with support for Network Interface Controller (NIC) Teaming. NOTE: On an Aggregator, all ports are configured by default as members of all (4094) VLANs, including the default VLAN. All VLANs operate in Layer 2 mode. You can reconfigure the VLAN membership for individual ports by using the vlan tagged or vlan untagged commands in INTERFACE configuration mode. See VLAN Membership for more information. Managing the MAC Address Table On an Aggregator in VLT and PMUX modes, you can manage the MAC address table by: • Clearing the MAC Address Entries • Displaying the MAC Address Table In the Standalone mode, use the show cam mac stack-unit 0 port-set 0 command to view the mac-addresses. The Aggregator auto-configures with support for Network Interface Controller (NIC) Teaming. Clearing the MAC Address Entries Learned MAC addresses are entered in the table as dynamic entries, which means that they are subject to aging. For any dynamic entry, if no packet arrives on the switch with the MAC address as the source or destination address within the timer period, the address is removed from the table. The default aging time is 1800 seconds in PMUX mode and 300 seconds in Standalone and VLT modes. You can manually clear the MAC address table of dynamic entries. To clear a MAC address table, use the following command: 1. Clear a MAC address table of dynamic entries. EXEC Privilege mode clear mac-address-table dynamic {all | interface {tengigabitethernet | SLOT/PORT} } • all: deletes all dynamic entries. • interface: deletes all entries for the specified interface.
