Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
hw-module uplink select
chassis, you can choose to use the 10-Gigabit Ethernet uplink ports, the Gigabit Ethernet uplink ports,
or all uplink ports. If you choose to use all uplink ports, then the tenth slot will support only the
WS-X4302-GB switching linecard. Be aware that this command takes effect only after a reload (after
you have executed the redundancy reload shelf command).
Because the uplink selection is programmed into hardware during initialization, changing the active
uplinks requires saving the configuration and reloading the switch. When you are configuring a change
to the uplinks, the system responds with a message informing you that the switch must be reloaded and
suggesting the appropriate command (depending on redundancy mode) to reload the switch.
If you select the all keyword, ensure that the tenth slot is either empty or has a WS-X4302-GB switching
module.
A no form of this command does not exist. To undo the configuration, you must configure the uplinks.
For Supervisor Engine 7L-E in a WS-C4507R chassis , the number of uplink options depends on the
supervisor engine mode (single or redundandant) and the uplink mode configuration (1-Gigabit or
10-Gigabit)
Single Supervisor Mode
In single supervisor mode, Supervisor Engine 7L-E supports the uplink configuration of at most either
two 10-Gigabit or four 1-Gigabit ports (Table 2-6).
Redundant Supervisor Mode
In redundant supervisor mode, Supervisor Engine 7L-E support 1+1 (in 10-Gigabit mode) and 2+2 (in
1-Gigabit mode) (Table 2-7).
Note No redundancy support exists for slots 3 and 4.
