This article will do a summary about the most frequently used Connectrix command for Cisco and Brocade san switch. It supposed to be a good handy reference for SAN troubleshooting and administration. All of the following commands are operated by the admin account or equal privilege.

Collecting Support log
The support log can be using for troubleshooting. It’s a pre-requisite to create a switch case to get technical help from the connectivity support engineer.
                Cisco:
                show tech-support details
                Brocade:
                supportshow
                supportsave
                Note:
                The outputs of command “show tech-support details”and“supportshow” are very long. Usually, we will use putty to capture all of the outputs and redirect into the session log in txt format. The output of command “supportsave” is a compressed file in Gzip format and aftp server is needed for storing.

Showing Switch firmware
                It’s always recommended to upgrade the firmware into the newest version. The known issues may be fixed in the newer version and the older version may be end of support life.
                Cisco:
show version
Example:
Switch# show version
Cisco Nexus Operating System (NX-OS) Software
…
  System version: 5.2(8) –the switch firmware (NX-OS) version is 5.2(8)
…
                Brocade:
                firmwareshow
                Example:
                FabricAdmin:switch> firmwareshow
Appl     Primary/Secondary Versions
------------------------------------------
FOS      v6.4.3c – the switch firmware (FOS) version is v6.4.3c
         v6.4.3c

Showing IP address of Management port
The management port of SAN switch is on Ethernet and only for management purpose.
Cisco:
show interface mgmt 0
Example:
Switch# show interface mgmt 0
mgmt0 is up
    Hardware is GigabitEthernet
    Address is 001d.a20f.a998
    Internet address is 10.32.167.226/24               - IPv4 address of management interface
    MTU 1500 bytes, BW 100 Mbps full Duplex
    14702321 packets input, 1271551817 bytes
      28651 multicast frames, 0 compressed
      0 input errors, 0 frame
      0 overrun, 0 fifo
    1100201 packets output, 134319443 bytes
      0 underruns, 0 output errors
      0 collisions, 0 fifo
      0 carrier errors
Brocade:
