ICX6610 Brocade Switch – Firmware

Ok, so I’m in the process of configuring our spare icx 6610 brocade switch with the same firmware and configuration of one of our main border WAN icx 6610’s that’s running BGP. If our router fails, then I will have a hot spare ready to go while I wait for an RMA. This requires that the space icx 6610 is running router firmware along with an icx 6610 advanced license. The icx 6610 has the ability to run in layer 2 switching mode only or layer 3 mode when the proper firmware is loaded. By default, I had two code versions loaded on the icx 6610. You can identify which code is which by looking at the flash file name. Running the show flash command will give you the following:

#show flash
Stack unit 1:
Compressed Pri Code size = 7189206, Version:07.4.00cT7f3 (FCXR07400c.bin)
Compressed Sec Code size = 8874046, Version:08.0.00aT7f3 (FCXR08000a.bin)
Compressed Boot-Monitor Image size = 370733, Version:07.3.03T7f5
Code Flash Free Space = 49020928

You want to look at the character after FCX in parentheses, I have (FCXR07400c.bin) and (FCXR08000a.bin). The fourth character is an R, which is for routing. If the letter was an S, then that would represent switching only. Right now, I have two different routing versions. Since this is a major rev., there was also a new boot code as well (07.3.03T7f5). Unfortunately, there’s not two slots in the flash to have two different boot codes. If I try to boot back to the 7.4 code, I won’t have the proper boot code that I had before. I will therefore copy another version 8 code to the primary flash space. To do that I will run the following command:

#copy tftp flash <ip-of-tftp-server> <flash-image> primary

In order to boot to the new flash (assuming you don’t need a new boot code), you can then run the following command:

#boot system flash <primary | secondary>

HINT: The default boot is set to boot from the primary location, so if you reboot again without running another command, it will boot back to the default location. If you want to always boot from the secondary flash location, run the following command in config t mode:

(config)#boot system flash secondary

Don’t forget to write mem.

  • Good posting. Have you had any issues while on the 7400 code while running BGP?

    • I have our primary WAN icx 6610 running version 7.4.00cT7f3 and our secondary icx 6610 WAN router running 8.0.00aT7f3. I haven’t had any issues with peer’s dropping. However, we are only allowing a few routes in. Nothing fancy. What kind of issues are you seeing?

      • Sorry for the delay. I only have one client using bgp on the 6610. It’s actually been a while since I have been there, so I assume he is still on 7300. But I haven’t heard from him, so I guess he is ok.
