LABEL DESCRIPTION
LACP Priority Type a number between 1 and 65,535 for the LACP system priority. The switch with the
lowest system priority (and lowest port number if system priority is the same) becomes
the LACP “server”. The LACP “server” controls the operation of LACP setup. Enter a number
to set the priority of an active port using Link Aggregate Control Protocol (LACP). The
smaller the number, the higher the priority level.
LACP Timeout LACP timeout is the time interval between the individual port exchanges of LACP packets in
order to check that the peer port in the trunk group is still up. If a port does not respond
after three tries, then it is deemed to be “down” and is removed from the trunk. Set a
short timeout (one second) for busy trunked links to ensure that disabled ports are
removed from the trunk group as soon as possible. Select either short (1 second) or long
(30 seconds).
Group ID This column displays the names of the trunk groups for the management switch card’s
Ethernet ports. In the MSC1000G, tsub is for the subtending ports and tup is for the
uplink ports.
Active Select this check box to turn on a trunk group.
Dynamic (LACP) Select this check box to use Link Aggregate Control Protocol (LACP), to dynamically create
and manage the trunk group.
Port This column lists the management switch card’s Gigabit Ethernet interfaces.
Group This column displays to which trunk group an MSC Gigabit Ethernet interface belongs.
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The
system loses these changes if it is turned off or loses power, so use the Config Save link
on the navigation panel and then the Save button to save your changes to the non-volatile
memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
