Mac address-table static. Adds static entries to the MAC address table or configures a static MAC address with IGMP snooping disabled for that address. Show mac address-table aging-time. Displays information about the time-out values for the MAC address table. Show mac address-table count. Displays the number of entries currently in the MAC. What would be ideal would be something like the 'show mac address-table interface' command, but for an interface range rather than a specific interface: This is the type of output I'm looking for, with each mac address listed for the port in question: switchxxx#show mac address-table interface g3/0/11 Mac Address Table-Vlan Mac Address Type.
I have seen cases where there were different customers using the same MAC address, on different VLANs; this was visible in 'show mac address-table' on a single PowerConnect 5324, and it seemed to be working fine. This is with all ports as Access Mode or Trunk Mode. I know 300 is the default mac address ageing time. Access-switch# show mac address-table aging-time Global Aging Time: 300 Vlan Aging Time- -But on one of the core switch it was showing a value 15000 along with 300. Core-switch# show mac-address-table aging-time Vlan Aging Time- -Global 15000 no vlan age other than global age. Show mac address-table aging-time vlan vlan-id Syntax Description. Vlan vlan-id (Optional) Displays information for a specific VLAN only; the range of valid values is from 1 to 4094. Defaults None Command Modes Any command mode Supported User Roles.

A number of different information types, terms, and names for data are thrown at all new networking students. Two of these information sources are vital to basic networking: Media Access Control (MAC) tables and Address Resolution Protocol (ARP) tables. Without at least a basic understanding of how these tables are used, it is hard to comprehend how information passes through a network. This article takes a look at each of these information sources, how they are used in the transmission of network traffic, and how they work together to move data from point A to point B.

doesn't necessarily mean its associated to VLAN2. it just means that MAC Address was learned on fa0/3 and it resides on VLAN2. because its a trunk port...if this was a trunk to another switch, you may see something like:
