Web Agent Procedure

To filter the AFT using the Web Agent:

1. Select Address Search from the Address Forwarding Table group on the Web Agent window. The Address Entry Search dialog box opens (Figure 9-4)

Figure 9-4. Address Entry Search Dialog Box.

NOTE: DISPLAY ALL ignores any parameter not checked in the left column. To view all addresses in the table, select DISPLAY ALL without selecting any filters.

2. To search using a MAC Address:
• Select the MAC Address check box in the Search By: column
• Enter a MAC address in the Search Value column.

NOTE: You must enter the complete MAC address.

3. To search using a VLAN:
• Select the VLAN check box in the Search By: column
• Select a VLAN name from the VLAN field pull-down menu in the Search Value: column.
4. To search using a Port:
• Select the Port check box in the Search By: column
• Select a search variable from the Port field pull-down menu. The options are: Forward, Filter, and CPU
• Enter a port number to display only the entries associated with that switch port.
5. To search using a bridging status:
• Select the Status check box in the Search By: column
• Select a status from the pull-down menu to show only ports of a specific bridging status. The options are: Learned, Management, Self, and Multicast.
6. Select DISPLAY ALL to open the Address Forwarding Table dialog box (Figure 9-5).

Figure 9-5. Address Forwarding Table Dialog Box

NOTE: Some types of entries in the Address Forwarding Table can be modified. The port, priority, and persistence can be changed for learned and management entries.

7. To change an entry in the Address Forwarding Table, select the check box in the Index column for MAC address entry.
8. Make the change(s) to the port, priority, or Persistence for the selected entry
9. After making the changes, click the APPLY button to save the current settings, or CANCEL to restore previous settings. or MORE to view more statistics.
10. See Table 9-4 to review your search criteria options:

    Table 9-4. Address Forwarding Table Parameters

    Parameter	Defines the...
    Index	Index number of this address entry in the switch address forwarding table.
    MAC Address	MAC address associated with this entry. This address is learned by the switch as an address to forward to the associated port.
    Port	Port associated with this MAC address table entry.
    Valid	An entry is valid until it ages out, at which time it becomes invalid. Aging out occurs when a frame with the entry's MAC address is not received during the address age time interval. An invalid entry can become a valid entry again if the entry's MAC address is learned (frame is received) during the super age time interval. If the super age time interval expires before the MAC address is learned again, the entry is deleted."
    Group	Group number associated with this MAC address.
    TblInst	Address table instance number associated with this MAC address.
    Priority	Priority level associated with traffic forwarded to this MAC address. The options are: Normal High You can set this parameter on all learned entries.
    Persistence	The persistence of the entry in the table can be set on all learned entries: Permanent - The address is not aged out of the table. Invalid - This entry is cleared from the table each time the switch resets. Ageout - Address is cleared from the address forwarding table when the timeout interval expires. This is the state of all entries dynamically learned by the switch. It ensures that MAC addresses that are not active on the network do not remain in the switch address forwarding table indefinitely. NOTE: Note: If you create a static, filtered MAC address and set Persistence to Ageout, the switch does not filter the MAC address. The switch continues to forward frames that have the MAC address for a source address or destination address. To correct this, set Persistence to Permanent.
    Status	The status of the address entry. Options include: Learned Management Self AFT Self Entries: 01:80:C2:00:00:00 - 01:80:c2:00:00:0F - 802.1D reserved addresses, the first entry is the Spanning Tree BPDU destination address. 09:00:4E:00:01:02 - 3Com Vlan Trunk (VLT) control frame address. Used for Spanning Tree blocked ports that are in 3Com tagging mode and connected to a port on the other side of a connection that is blocked by Spanning Tree. 01:00:0C:CC:CC:CC - Cisco control frame. Used to synchronize VLAN membership across switches (VTPs) or router information between routers (CDPs). The switch sends them to the CPU, the CPU will set the BPDU bit when transmitting out a port trunking ISL. 01:00:0C:DD:DD:DD - If Cisco Group Management Protocol (CGMP) is enabled, the switch may listen to gather multicast group information
