Behavior changes in Quad Port group speed configuration between 8095 and 9010 firmware version

[Chandini]

Behavior noticed:

ICX7850-48F Router(config)#interface eth 1/1/1

ICX7850-48F Router(config-if-e25000-1/1/1)#speed-duplex 10g-full

This speed is not allowed on port 1/1/1 due to quad portgroup speed restriction(portgroup: 1/1/1 to 1/1/4)

ICX7850-48F Router(config-if-e25000-1/1/1)#

ICX7850-48F Router(config-if-e25000-1/1/1)#end

Applicable ICX switch model:

• 7850-48F

If the switches are running version 8095 and below, then the below details will help you configure the quad port setting:

If the switches are running version 8095 and below, then there is a workaround which will help you set individual ports to 10g or 1g.

Example:

In this case switch is running 8095m version

ICX7850-48F Router(config)#int e 1/1/9 to 1/1/12

ICX7850-48F Router(config-mif-1/1/9-1/1/12)#speed-duplex 10g-full

ICX7850-48F Router(config-mif-1/1/9-1/1/12)#exit

ICX7850-48F Router(config)#int e 1/1/9

ICX7850-48F Router(config-if-e25000-1/1/9)#speed-duplex 1000-full

ICX7850-48F Router(config-if-e25000-1/1/9)#exit

From running configuration 8095m

!

interface ethernet 1/1/9

 speed-duplex 1000-full

!

interface ethernet 1/1/10

 speed-duplex 10G-full

!

interface ethernet 1/1/11

 speed-duplex 10G-full

!

interface ethernet 1/1/12

 speed-duplex 10G-full

Port speed for port groups, cannot be changed individually. If required, the speed must be changed to all ports in the same quad-group and then we would be able to change speed to 1g on individual ports. This was a workaround in versions 8095 and below.

If the switches are running version 9010 and above versions, then the below details will help you configure the quad port setting:

If the switches are running version 9010 and above, then there is no workaround which will help change speed on interfaces. It is only considering four ports in group to be set to same speed.

Example:

In this case switch is running 10.0.10b version

ICX7850-48F Router(config)#int e 1/1/10

ICX7850-48F Router(config-if-e25000-1/1/10)#speed-duplex 1000-full

This speed is not allowed on port 1/1/10 due to quad portgroup speed restriction(portgroup: 1/1/9 to 1/1/12)

From versions 9010 and above in 7850-48F model speed settings is a design change to maintain consistency to the port group.
