Optimizing Port Usage Through Traffic Control and Port Trunking
Viewing Port Status and Configuring Port Parameters
Optimizing Port Usage
Through Traffic Control and
Using the CLI To Configure Ports. You can configure one or more of the
following port parameters. For details on each option, see Table 6-1 on page
6-3.
Syntax: [no] interface <[ethernet] port-list>
[disable | enable]
[speed-duplex
<auto-10 |10-full |
10-half |
100-full | 10
0-half |auto|
1000-full |>]
[flow-control]
[broadcast-limit <0 - 99>]
Note that in the above syntax you can subsitute an “int” for “interface” and an
“e” for “ethernet”; that is int e <port-list>.
For example, to configure ports 1 through 4 and port 7 for 100Mbps full-duplex
with a broadcast limit of 20%, you would enter this command:
HP2512(config)# int e 1-4,7 speed-duplex 100-full
broadcast-limit 20
Similarly, to configure a single port with the settings in the above command,
you could either enter the same command with only the one port identified,
or go to the context level for that port and then enter the command. For
example, to enter the context level for port 7 and then configure that port for
100FDx with a broadcast limit of 20%:
HP2512(config)# int e 7
HP2512(eth-7)# speed-duplex 100-full broadcast-limit 20
If port 8 was disabled, and you wanted to enable it and configure it for 100FDx
with a broadcast limit of 20%, with flow-control active and a broadcast limit
of 20%, you could do so with either of the following command sets.
■ This command enables and configures port 8 from the config level:
HP2512(config)# interface e 8 enable speed-duplex
100-full broadcast-limit 20 flow-control
■ These two commands select the context level for port 8 and then apply
all of the configuration commands to port 8:
HP2512(config)# int e 8
HP2512(eth-8)# enable speed-duplex 100-full
flow-control broadcast-limit 20
