MAC Address Table
JetNet 5020G provides 16K entries in MAC Address Table. In this page, users can change
the Aging time, add Static Unicast MAC Address, monitor the MAC address or sort them by
different packet types and ports. Click on
Apply
to change the value.
Aging Time (Sec)
Each switch fabric has limit size to write the learnt MAC address. To save more entries for
new MAC address, the switch fabric will age out non-used MAC address entry per Aging
Time timeout. The default Aging Time is 300 seconds. The Aging Time can be modified in
this page.
Static Unicast MAC Address
In some applications, users may need to type in the static Unicast MAC address to its MAC
address table. In this page, you can type MAC Address (format: xxxx.xxxx.xxxx), select its
VID and Port ID, and then click on
Add
to add it to MAC Address table.
MAC Address Table
In this MAC Address Table, you can see all the MAC Addresses learnt by the switch fabric.
The packet types include Management Unicast, Static Unicast, Dynamic Unicast, Static
Multicast and Dynamic Multicast. The table allows users to sort the address by the packet
types and port.
Packet Types:
Management Unicast
means MAC address of the switch. It belongs to
CPU port only.
Static Unicast
MAC address can be added and deleted.
Dynamic Unicast
MAC is MAC address learnt by the switch Fabric.
Static Multicast
can be added by CLI
and can be deleted by Web and CLI.
Dynamic Multicast
will appear after you enabled
IGMP and the switch learnt IGMP report.
Click on
Remove
to remove the static Unicast/Multicast MAC address. Click on
Reload
to
refresh the table. New learnt Unicast/Multicast MAC address will be updated to MAC
address table.
