Chapter 2. Commands for MAC Address Table Configuration 37

www.qtech.ru

 Usage Guide: If enable port-security, private-vlan, mac-notification, mac-limit, etc., it

should enable MAC learning through CPU first.

 Example: Enable MAC learning through CPU.

 Switch(Config)#mac-address-learning cpu-control

2.1.5 mac-address-table aging-time

 Command: mac-address-table aging-time <0 | aging-time>

 no mac-address-table aging-time

 Function: Sets the aging-time for the dynamic entries of MAC address table.

 Parameter: <aging-time> is the aging-time seconds, range from 10 to 1000000; 0 to

disable aging.

 Command Mode: Global Mode.

 Default: Default aging-time is 300 seconds.

 Usage Guide: If no destination address of the packets is same with the address entry in

aging-time, the address entry will get aged. The user had better set the aging-time

according to the network condition, it usually use the default value.

 Example: Set the aging-time to 600 seconds.

 Switch(config)#mac-address-table aging-time 600

2.1.6 mac-address-table static | static-multicast | blackhole

 Command: mac-address-table {static | static-multicast | blackhole} address <mac-

addr> vlan <vlan-id> [interface [ethernet | portchannel] <interface-name>] | [source

| destination | both]

 no mac-address-table {static | static-multicast | blackhole | dynamic}

[address <mac-addr>] [vlan <vlan-id>] [interface [ethernet |

portchannel] <interface-name>]

 Function: Add or modify static address entries, static multicast entries and filter

address entries. The no command deletes the three entries.

 Parameter: static is the static entries; static-multicast is the static multicast entries;

blackhole is filter entries, which is for discarding frames from specific MAC address, it

can filter source address, destination address or the both. When choose the filter

entries, blackhole address can’t based on port, and not configure to interface; dynamic

is dynamic address entries; <mac-addr> MAC address to be added or deleted;

<interface-name> name of the port transmitting the MAC data packet; <vlan-id> is the

vlan number. source is based on source address filter; destination is based on

destination address filter; both is based on source address and destination address

filter, the default is both.

 Command Mode: Global Mode

 Default: When VLAN interface is configured and is up, the system will generate a static

address mapping entry of which the inherent MAC address corresponds to the VLAN

number.
