Description
In the Routing table:
The status of the routing entry.
• Valid - The route is functional.
• Invalid - The route is non-functional. This
could be because the port is down or disabled.
In LES configuration:
The operational state of the LES. When in the Up
state, the LES will respond to LEC requests.
The current UNI (User to Network Interface)
termination on the root virtual port. This can be
either on the user side or network side.
The name of the manager.
The device type.
The name of the PNNI routing domain in which
this node participates.
The name of the PNNI routing domain in which
this node participates.
There are two packet discard thresholds for each
option card, called Early Packet Discard (EPD) and
Partial Packet Discard (PPD). By default, both
thresholds have a default set limit and are enabled.
The Avaya M770 ATM Device uses EPD to discard
entire AAL5 frames for ABR and UBR traffic (rather
than random cells from different frames), when it
determines that it is about to become congested.
The Avaya M770 ATM Device passes through the
last cell of each AAL5 frame so that end stations are
aware that a discard has taken place. You can
configure a threshold at which the EPD will be
invoked. The threshold is a percentage of the
overall shared buffer space.
The name of the ELAN.
The type of ELAN. Possible types are:
• Ethernet
• Token Ring
The End Station Identifier (ESI) is the MAC address
of the master agent. The ATM address of the switch
consists of the ATM prefix and the ESI.
