Description
The MAC address of the bridge.
The Avidia system currently supports transparent bridging only.
The number of entries deleted from the Bridging Table because the
Bridging Table has reached the maximum allowable size (4K).
The STP protocol version in use by the system. The only option
currently supported by the system is: ieee8021d—IEEE 802.1d
implementations.
The number of seconds after which forwarding information will be
deleted from the Bridging Table if it is not re-learned.
The number of seconds that have passed since the STP's learned
physical topology of the system last changed.
The number of times the STP's learned physical topology of the
system has changed since the management card was last reset.
The MAC address of the bridge that is designated as the root, or base,
of the STP topology.
The cost of the path from the bridge port to the designated root. The
range is from 1 to 65535, with 1 indicating the lowest cost.
The bridge port that is chosen by the STP to forward traffic to the root.
The maximum age value currently in use in the network, which is
determined by the STP root system. This value may be different than
the configured maximum age within the system. The maximum age is
the number of seconds after which STP entries in the Bridging Table
will be deleted if they are not re-learned.
The maximum hello time currently in use in the network, which is
determined by the STP root system. This value may be different than
the configured maximum hello time within the system. The maximum
hello time is the interval, in seconds, at which you want the system to
send STP packets.
The maximum hold time is the interval during which no more than two
bridge BPDUs should be transmitted by the system. In the Avidia
system this value is always 1 (one second).
The maximum forward delay currently in use by the system, which is
determined by the STP root system. This value may be different than
the configured maximum forward delay within the system. The
maximum forward delay is the number of seconds you want the
system to wait before changing the STP state of a particular interface.
