The switch’s configuration maintains the swapped-out settings. These
result in error messages on start-up, but do not affect the functioning of the
switch. The configuration can be manually edited to remove the swapped
sections that no longer apply.
4. Line Card 1 has been configured and then removed before the configuration
was saved using the create config command. The user then wishes to enter
this command, while keeping the previous configuration of the line card
that has been hot swapped out.
When the create config command is entered, the switch retains the
configuration of the line card that has been hot swapped out. For example,
if the original configuration included the command add vlan=”V2”
port=1.1-2.4
, the show config dynamic command would display the
following configuration even though ports 1.1-1.8 no longer exist:
#
# vlan configuration
#
add vlan="v2" port=1.1-1.8
add vlan="v2" port=2.1-2.4
If the switch is then restarted, some of the commands fail and the resulting
dynamic configuration is:
#
# vlan configuration
#
add vlan="v2" port=2.1-2.4
#
# vlan swapped out port configuration
add vlan="v2" port=1.1-1.8
This situation is potentially problematic because the switch has been
restarted before the line card was hot swapped back in. The remaining
examples describe possible ramifications.
5. (continuing from the end of Example 4) The switch is powered down and a
different type of line card (for example, a 48-port line card) is inserted into
slot 1. The switch is then powered up.
Ports 1.1-1.8 are configured as they were for the original 8-port line card.
The remaining ports are added to the default VLAN.
Ultimately the line card is initialised to match as many of the commands
that were previously configured as possible (some settings such as port
speed are not possible).
6. (continuing from the end of Example 4) A line card is inserted into slot 1,
and the configuration saved by using the command:
create config
The line card is initialised without configuration because the commands
stored in the swapped out configuration that refer to this slot are all
removed when the user creates a configuration.
Before the new line card was inserted, the configuration displayed by the
show config dynamic
command would have been:
#
# vlan configuration
