mac-address-table static

Use this command to map a static address to a port in a VLAN. Use the no form to remove an address.

Syntax

mac-address-table static mac-address interface vlan vlan-id [action]
no mac-address-table static mac-address vlan vlan-id

  • mac-address - MAC address.
  • interface
    • ethernet unit/port
      • unit - This is device 1.
      • port - Port number.
    • port-channel channel-id (Range: 1-6)
  • vlan-id - VLAN ID (Range: 1-4094)
  • action -
    • delete-on-reset: Assignment lasts until switch is reset.
    • permanent: Assignment is permanent.

Default Setting

No static addresses are defined. The default mode is permanent.

Command Mode

Global Configuration

Command Usage

  • The static address for a host device can be assigned to a specific port within a specific VLAN. Use this command to add static addresses to the MAC Address Table. Static addresses have the following characteristics:
    • Static addresses will not be removed from the address table when a given interface link is down.
    • Static addresses are bound to the assigned interface and will not be moved. When a static address is seen on another interface, the address will be ignored and will not be written to the address table.
    • A static address cannot be learned on another port until the address is removed with the no form of this command.
  • The maximum number of address entries -
    • PowerConnect 3248: 8191
    • PowerConnect 5224: 32768

Example

Console(config)#mac-address-table static 00-e0-29-94-34-de ethernet 1/1 vlan 1 delete-on-reset
Console(config)#


clear mac-address-table dynamic

Use this command to remove any learned entries from the forwarding database and to clear the transmit and receive counts for any static or system-configured entries.

Default Setting

None

Command Mode

Privileged Exec

Example

Console#clear mac-address-table dynamic
Console#


show mac-address-table

Use this command to view classes of entries in the bridge-forwarding database.

Syntax

show mac-address-table [address mac-address [mask]] [interface interface] [vlan vlan-id] [sort {address | vlan | interface}]

  • mac-address - MAC address.
  • mask - Bits to match in the address.
  • interface
    • ethernet unit/port
      • unit - This is device 1.
      • port - Port number.
    • port-channel channel-id (Range: 1-6)
  • vlan-id - VLAN ID (Range: 1-4094)
  • sort - Sort by address, vlan or interface.

Default Setting

None

Command Mode

Privileged Exec

Command Usage

  • The MAC Address Table contains the MAC addresses associated with each interface.
  • The Type field may include the following types:
    • Learned - dynamic address entries
    • Permanent - static entry
    • Delete-on-reset - static entry to be deleted when system is reset
  • The mask should be hexadecimal numbers (representing an equivalent bit mask) in the form xx-xx-xx-xx-xx-xx that is applied to the specified MAC address. Enter hexadecimal numbers, where an equivalent binary bit “0” means to match a bit and “1” means to ignore a bit. For example, a mask of 00-00-00-00-00-00 means an exact match, and a mask of FF-FF-FF-FF-FF-FF means "any."
  • The maximum number of address entries -
    • PowerConnect 3248: 8191
    • PowerConnect 5224: 32768

Example


mac-address-table aging-time

Use this command to set the aging time for entries in the address table. Use the no form to restore the default aging time.

Syntax

mac-address-table aging-time seconds
no mac-address-table aging-time

  • seconds - Time is number of seconds
    (PowerConnect 5224: 17-2148; PowerConnect 3248: 10-1000000).

Default Setting

300 seconds

Command Mode

Global Configuration

Command Usage

The aging time is used to age out dynamically learned forwarding information.

Example

Console(config)#mac-address-table aging-time 300
Console(config)#


show mac-address-table aging-time

Use this command to show the aging time for entries in the address table.

Default Setting

None

Command Mode

Privileged Exec

Example

Console#show mac-address-table aging-time
 Aging time: 300 sec.
Console#
