Mac-Address-Table Static | Static-Multicast | Blackhole - Planet Networking & Communication SGS-6340-24T4S Command Manual

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

Command:
mac-address-table {static | static-multicast | blackhole} address <mac-addr> vlan <vlan-id> [interface
ethernet <interface-name>] | [source | destination | both]
no mac-address-table {static | static-multicast | blackhole | dynamic} [address <mac-addr>] [vlan <vlan-id>]
[interface ethernet <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.
Usage Guide:
In certain special applications or when the switch is unable to dynamically learn the MAC address, users can use this
command to manually establish mapping relation between the MAC address and port and VLAN.
no mac-address-table command is for deleting all dynamic, static, filter MAC address entries existing in the switch
MAC address list, except application, system entries. MAC address entries can be classified according to the
different source, the types are as follows: DYNAMIC, STATIC, APPLICATION, SYSTEM. DYNAMIC is the dynamic
MAC address entries learned by switch, it can be aged by switch automatically. STATIC is the static MAC address
entries (including blackhole entries) added by user. APPLICATION is the static MAC address entries added by
application protocol (such as dot1x, security port...). SYSTEM is the additive static MAC address entries according
to VLAN interface. When adding STATIC entries, it can cover the conflictive DYNAMIC, except APPLICATION,
SYSTEM entries.
