Adjusting the Keepalive Timer
To change the time interval between keepalive messages on the interfaces, use the keepalive command. The interface sends keepalive
messages to itself to test network connectivity on the interface.
To change the default time interval between keepalive messages, use the following command.
• Change the default interval between keepalive messages.
INTERFACE mode
keepalive [seconds]
• View the new setting.
INTERFACE mode
show config
View Advanced Interface Information
The following options have been implemented for the show [ip | running-config] interfaces commands for (only) stack-
unit interfaces.
When you use the configured keyword, only interfaces that have non-default configurations are displayed. Dummy stack-unit
interfaces (created with the stack-unit command) are treated like any other physical interface.
The following example lists the possible show commands that have the configured keyword available:
Dell#show interfaces configured
Dell#show interfaces stack-unit 1 configured
Dell#show interfaces tengigabitEthernet 1 configured
Dell#show ip interface configured
Dell#show ip interface stack-unit 1 configured
Dell#show ip interface tengigabitEthernet 1 configured
Dell#show ip interface br configured
Dell#show ip interface br stack-unit 1 configured
Dell#show ip interface br tengigabitEthernet 1 configured
Dell#show running-config interfaces configured
Dell#show running-config interface tengigabitEthernet 1 configured
In EXEC mode, the show interfaces switchport command displays only interfaces in Layer 2 mode and their relevant
configuration information. The show interfaces switchport command displays the interface, whether it supports IEEE 802.1Q
tagging or not, and the VLANs to which the interface belongs.
