Table 3 Status and parameters for each port type (continued)
DescriptionStatus or parameter
Flow control
• Disabled (default): The port does not generate flow control packets, and drops any
flow control packets it receives.
• Enabled: The port uses 802.3x link layer flow control, generates flow-control packets,
and processes received flow-control packets.
With the port mode set to Auto (the default) and flow control enabled, the switch
negotiates flow control on the indicated port. If the port mode is not set to Auto, or if
flow control is disabled on the port, flow control is not used. Note that flow control must
be enabled on both ends of a link.
Specifies the percentage of the theoretical maximum network bandwidth that can be
used for broadcast traffic. Any broadcast traffic exceeding that limit will be dropped.
Zero (0) means the feature is disabled.
Broadcast limit
The broadcast-limit command operates at the port context level to set the broadcast limit
for a port on the switch.
NOTE: This feature is not appropriate for networks that require high levels of IPX or
RIP broadcast traffic.
Error messages associated with the show interfaces command
Error messageError
Total length of selected data exceeds one lineRequesting too many fields (total characters exceeds 80)
Invalid input: inputField name is misspelled
Module not present for port or invalid port: inputMistake in specifying the port list
Incomplete input: customThe port list is not specified
Using pattern matching with the show interfaces custom command
If you have included a pattern matching command to search for a field in the output of the show
int custom command, and the show int custom command produces an error, the error
message may not be visible and the output is empty. For example, if you enter a command that
produces an error (such as vlan is misspelled) with the pattern matching include option, the
output may be empty:
[ (HP_Switch_name#) show int custom 1-3 name vlun | include
vlan1 ]
It is advisable to try the show int custom command first to ensure there is output, and then
enter the command again with the pattern matching option.
Note that in the above command, you can substitute int for interface; that is: show int
custom.
About configuring auto-MDIX
Copper ports on the switch can automatically detect the type of cable configuration (MDI or MDI-X)
on a connected device and adjust to operate appropriately.
This means you can use a "straight-through" twisted-pair cable or a "crossover" twisted-pair cable
for any of the connections—the port makes the necessary adjustments to accommodate either one
