Stacking (VSF) Aruba Switches
KB ID 0001492 I noticed some shiny Aruba switches on the bench today, they were for a job my colleague is working on. (Note: Each switch in a stack should be the same model, so these will need two stacks!) I work on the occasional HP/Aruba core switch, but it’s been a while since I did any work on distribution switches like these. The first thing I learned, was there’s no dedicated stacking cable for them. They simply use...
Cisco Error ‘%PHY-4-SFP_NOT_SUPPORTED’

Cisco IOS – Configuring Switch to Switch MACSEC
KB ID 0001000 Problem My colleague had to set this up on the test bench today, and it looked infinitely more interesting that what I was doing, so I grabbed my console cable, and offered to ‘help’. This was done on two Cisco Catalyst 3560-X switches, each with a 10G Service Module (C3KX-SM-10G), and 1Gb SFP modules (Note: Not 10Gb ones, this will become important later). Solution 1. First hurdle was, when we tried to add...
Cisco Catalyst – ‘Daughtercard inserted in this switch may not have been manufactured by Cisco’
KB ID 0001018 Problem In a newly deployed switch, the MACSEC link refused to establish, when I consoled in I was greeted with this; Dec 06 01:30:07.023: %ILET-1-DEVICE_AUTHENTICATION_FAIL: The FRULink SM Daughtercard inserted in this switch may not have been manufactured by Cisco or with Cisco’s authorization. If your use of this product is the cause of a support issue, Cisco may deny operation of the product, support under...
Cisco ASA 5585-X Port Numbering
KB ID 0001004 Problem Back at the beginning of the year I had to do a firewall design that included an ASA5585-X, I did some searching to find out how the ports were numbered but came up blank. So I took an (incorrect) educated guess. I unboxed and fired one up today, and ran though the port numbering and orientation, and discovered the correct numbering. Solution Note: This ASA5585-X also has a CX module fitted. The bottom...
