Removing Dynamic MAC Address Entries

You can remove all dynamic (learned) MAC address entries from the forwarding table for a bridge group (using the clear bridge command) or for a bridge interface (using the clear bridge interface command). You can also use the clear bridge address command to remove a specific dynamic MAC address entry from the forwarding table for a bridge group.

clear bridge

• Use to remove all dynamic MAC address entries from the forwarding table for the specified bridge group.
• Example

  host1#show bridge westford01 table
    Bridge: westford01 MAC Address Table
     Address         Action         Interface          Age
  --------------   ----------   -------------------   -----
  0090.1a01.0205   forward      ATM3/3.1                0  
  1234.abcd.5678   discard      ---                    ---

  host1#clear bridge westford01
  
  

  host1#show bridge westford01 table
    Bridge: westford01 MAC Address Table
     Address         Action         Interface          Age
  --------------   ----------   -------------------   -----

clear bridge address

• Use to remove a specific dynamic MAC address entry from the forwarding table for the specified bridge group.

  host1#clear bridge westford01 address 1234.abcd.5678
  
  

  host1#show bridge westford01 table
    Bridge: westford01 MAC Address Table
     Address         Action         Interface          Age
  --------------   ----------   -------------------   -----
  0090.1a01.0205   forward      ATM3/3.1                0

• See clear bridge address.

clear bridge interface

• Use to remove all dynamic MAC address entries for a network interface belonging to a bridge group from the forwarding table for that bridge group.
• You must specify the following:
  • interfaceType—One of the following bridge interface types listed in Interface Types and Specifiers in JUNOSe Command Reference Guide:
    • atm
    • fastEthernet
    • gigabitEthernet
    • tenGigabitEthernet
  • interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers in JUNOSe Command Reference Guide for information
• Example

  host1#show bridge westford02 table dynamic
    Bridge: westford02 MAC Address Table
     Address         Action         Interface          Age
  --------------   ----------   -------------------   -----
  0090.1a01.0205   forward      ATM3/3.1                0  
  0090.1a01.0206   forward      ATM3/3.2               10  
  0090.1a01.0207   forward      ATM3/3.3                5  

  host1#clear bridge interface atm 3/3.2
  
  

  host1#show bridge westford02 table dynamic
    Bridge: westford02 MAC Address Table
     Address         Action         Interface          Age
  --------------   ----------   -------------------   -----
  0090.1a01.0205   forward      ATM3/3.1                0  
  0090.1a01.0207   forward      ATM3/3.3                5
