media-type Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands If you configure auto-select, you cannot configure the speed and duplex interface configuration commands. The switch operates with 1000BASE-X (where -X is -SX) SFP modules as follows: • When the 1000BASE -X SFP module is inserted into the module slot and there is no link on the RJ-45 side, the switch disables the RJ-45 interface and selects the SFP module interface. This is the behavior even if there is no cable connected and if there is no link on the SFP side. • When the 1000BASE-X SFP module is inserted and there is a link on the RJ-45 side, the switch continues with that link. If the link goes down, the switch disables the RJ-45 side and selects the SFP module interface. • When the 1000BASE-X SFP module is removed, the switch again dynamically selects the type (auto-select) and re-enables the RJ-45 side. Examples This example shows how to select the SFP interface: Switch(config)# interface gigabitethernet0/17 Switch(config-if)# media-type sfp You can verify your setting by entering the show interfaces interface-id capabilities or the show interfaces interface-id transceiver properties privileged EXEC commands.
