Optical SFPs Do Not Link Up on Edge-Core 5610

Follow

Issue

Links with Optical SFP+s on Edge-Core AS5610-52X will not come up.

cumulus@switch$ ip link show

3: swp1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast master test state DOWN mode DEFAULT qlen 500<


Environment

This affects all versions of Cumulus Linux from 2.2 and earlier

It only applies to the Edge-Core AS5610-52X. The Edge-Core AS5600-52X and other platforms are not affected.

Solution:

The fix for this issue is provided in a patch for Cumulus Linux 2.2.  

If you are running a version prior to Cumulus Linux 2.2, you must first upgrade.

Once Cumulus Linux 2.2 is installed on the switch, run:

cumulus@switch$ sudo apt-get update
cumulus@switch$ apt-get install cl-platform-config 
cumulus@switch$ reboot 

To confirm the update was successfully installed after the reboot, run:

cumulus@switch$ dpkg -l | grep cl-platform-config 
cl-platform-config 1.0-cl2.2+1 powerpc Installs hardware/platform dependent configuration files into /etc
