Upgrading or downgrading configuration considerations for PoD

Configuration considerations when configuring PoD

for ICX 6450 devices only

Consider the following when configuring PoD for ICX 6450 devices only:

• By default, without a license at bootup, ports 2 and 4 come up in 10 Gbps port speed in an

error disabled state. The show interface ethernet command displays the port in the

ERROR_DISABLED state at bootup. Refer to section, “Configuration considerations when

configuring PoD on an interface” on page 129 for output example from the show interface

ethernet command.

• From the default state, ports 2 and 4 can be configured to 1 Gbps port speed using the

speed-duplex 1000-full-master command without a license. You do not need to reboot the

switch for the links to come up in 1 Gbps port speed.

• If you download the ICX6450-2X10G-LIC-POD license to the device, insert the correct 10 Gbps

optic transceiver, and enter the speed-duplex 10g-full command on the interface, you can

immediately begin using ports 2 and 4 in 10 Gbps port speed. You do not need to reboot the

switch for the links to come up.

• For any of the four uplink ports on slot 2, if you re-configure any port from 1 Gbps to 10 Gbps

port speed, you must reload the switch to begin using the ports in 10 Gbps port speed. Until

you reload the switch, the ports will remain in an error-disabled state. The following example

output displays ethernet port 4 in an error-disabled state.
