clubs: | 12.4.15T10 Out
Anyone else been waiting on this? Cisco tells me this release is supposed to fix a few of our open issues. I guess we will see. |

| The ios ips auto-update command was almost useless, it seems they either partially or totally fixed it with t10 ( got it at 2 places so far and testing it).
Issue with some crashing due to a STACK LOW problem.
Few other issues here and there.
If everything looks good i will push this out to our ~125 sites next week and should see some improvement. |

| Some of those caveats are interesting... I had to laugh when I read this one -
CSCso05336
Symptoms: A Cisco 1811 router reloads when trying to connect to irc.freenode.net during the first 36 hours following a reload.
Conditions: The symptom is observed only in the first 36 hours following a reload.
Workaround: Do not connect to irc.freenode.net the first 36 hours following a reload.

We use 12.4(15)T9 on our 1841 and 2811 routers. I see Cisco also has 12.4(20), 12.4(22), and 12.4(24) tracks. Is there going to come a time when Cisco will merge all of these into a 12.5? Will there be some forced upgrades? I am curious as to what IOS version I would have to use in the event of a security vulnerability in, say, 20 months from now. 12.4(15) works fine for me so I'm not too excited to try 12.4(24). I understand the concept behind the "T" releases, but I don't know anything about their lifespan. The only other IOS I have worked with was mainline 12.2 and 12.4 which have been supported for a long long time. |

Going from one T release to another in the same train should just be bug fixes with no new feature. Going from one train to another will result in new/different features and new/different bugs.
It is sort of a mess, even our Cisco TAC guy thinks so. Apparently somewhere along the line they where going to go to a 12.5 T and Mainline release, but didnt.
I can say there are some major changes including new feateures going from 12.4 15 train to any of the 20, 22 or 24 tracks. It also reads some things differently in the config, to where i had to make several changes to our 15(t9) config to get it to work on a 20T release. |

| Since there are significant differences, do you think Cisco will make a MD/GD release of 12.4(15)T sometime? My company is rather small but relies heavily on a few routers. It would be nice to see a clear long-term IOS 12.4(15)T security update path that won't require having to learn new features or new configs we don't need. |

Franklin, TN | I was personally part of that IRC crash research. I was running a customized build for them for a while its odd how connecting to an IRC server caused severe IOS crashes. however it wasn't that IRC channel it was irc.gamesurge.net that i was on |

Funny stuff—though I’d be quite interested in knowing what at irc.freenode.net causes the reload. |

| Apparently it's not just irc.freenode.net. It's any IRC server running ircd-ratbox (prolly a specific build/all builds/who cares).
So i accidentaly DDoSed my home router by leaving Xchat open and i had a flashback to this thread.
I had 28 crashinfo files on the flash when i could log back in.

| I'm having some ugly surprises with 12.4.15T10 on Cisco 1811 platform.
A few reloads out of blue sky when the router was mostly idle.
Careful with this one into production. |

I don't know that you will see any 12.5 train now that they have jumped to version 15.0 for most models. |
