with a loop (or a network where someone inadvertently plugs the wrong cable into the wrong
ports) will lead to a complete cessation of all traffic. Rapid Spanning Tree is a fast-converging
protocol, faster than the ealier STP, that enables new ports much faster (sub-second) than the
older protocol. Rapid Spanning Tree works with all Avaya equipment, and can be
recommended.
Rapid Spanning Tree is set using the P330 stack processor command line interface.
To enable/disable spanning tree
1. Open a telnet session on the P330 stack processor, using the serial cable connected to the
Console port of the G700.
2. At the P330-x(super)# prompt, type
set spantree help
and press Enter to display the
set spantree commands selection.
3. To enable Spanning Tree, type
set spantree enable
and press Enter.
4. To set the rapid spanning tree version, type
set spantree version
rapid-spanning-tree
and press Enter.
The 802.1w standard defines differently the default path cost for a port compared to STP
(802.1d). In order to avoid network topology change when migrating to RSTP, the STP path
cost is preserved when changing the spanning tree version to RSTP. You can use the
default RSTP port cost by typing the CLI command
set port spantree cost auto
.
Note:
Note:
Avaya P330s now support a "Faststart" or "Portfast" function, because the
802.1w standard defined it. An edge port is a port that goes to a device that
cannot form a network loop.
To set an edge-port, type
set port edge admin state module/port
edgeport
.

Installing new firmware on the G700 Media Gateway Processor
To install MGP firmware
1. At the P330-1(configure)# prompt, type
session mgp
to reach the G700 media gateway
processor.
2. Type
configure
at the
MG-???-1(super)# prompt to enter configuration mode, which will
change the prompt to MG-???-1(configure)#.
3. At the MG-???-1(configure)#
prompt, type
show mgp bootimage
to determine which
disk partition (bank) is in the Active Now column.
You will update the bank that is not listed as Active Now. The system displays the following
screen:
