hi, were looking at various ios images to use so we can standardise across the network. were looking at ios version 11.2(9)P or 11.2(10)P does anyone have any warstories to share about these ? good points/bad points ? things i should be watch out for ? regards, stuart bryant stuartb@paradox.net.au cabinet maker/plumber paradox digital ph +61 8 9201 9201 f +61 8 9201 9200 founding member: fellowship of beer. i used to bite (tm)
Once being an advocate of bleeding edge, I have settled on 11.1.17(CA), which seems to be very stable. However, I am running 11.2.11P on two 4700's with HSSI's, which runs well (except for some unexplained frame-relay outages on one, which happens randomly). We are runng 11.1.17(CA) well on 2501's, and 7206's. On Wed, 11 Mar 1998, Stuart Bryant wrote:

They have 11.1(17.3)CAA with some bugs fixed, this is better than 11.1(17)CAA. But this IOS was not published, and should be requested personally. I think it's pre-release of 11.1(18)CAA. On Wed, 11 Mar 1998, Alex Rubenstein wrote:

We have to run the 11.2P series because of some particular VLAN bug fixes that have only been incorporated in 11.2 and 11.3. (Cisco wanted us to run 11.3.1 the day after it came out. I thanked them and said, "No." That image has since been withdrawn.) I am generally happy with 11.2.11P, but there is apparently a bug that causes f our RSP4 7513 to reload around 8 hours after a coldstart. (Fortunately, we don't power-cycle 7513s very often.) In general, I would recommend sticking with 11.1CA when possible. For one thing, it is the only version to support the VIP2-50 card. I have a brand-new VIP2-50 boxed up in a storage locker because I can't use it under 11.2P and Cisco says it will never be supported in either 11.2 or 11.3. When possible, I will probably back down one of our routers to 11.1CA so I can use the card. The 11.3 series does have some really nice features like HSRP for ISL VLANS, but I suspect it will be awhile before I try dropping that series on a production router. -dpm
stay away from 11.2(9)P if your using loopback interfaces for IGP. It has a nasty habit of turning the loopback0 interface into loopback-99 or some random negative integer.

On 7206's 11.(2)P is crash city so I wouldn't recommend it at all. 11.2(8) seems to run into a few strange problems too which we haven't been able to figure out. We are running 11.2(11)P on one 7206 without problems (so far). bye, ken emery

Looking at all these release numbers, I have only one observation to make: God, I'm glad I'm not Cisco's Release Engineering manager. Cheers, -- jra -- Jay R.

Upon its release, 11.2(11)P on a 7206 was so bad for us we had to back out of it within minutes of installing it. Cpu was pegged at 99%. The source of that may have just been discovered yesterday in 11.2(12)P (and 11.2(11.3)P) and was probably happening in 11.2(11)P and earlier. SHO ALIGN showed millions of misaligned memory references. The trace led to frame relay compression code. Even turning ALL F/R compression off still had the problem because the code path was still there until the next reload. This is now CSCds87720. The port with the problem is on a PA-8T. FWIW F/R compression runs well in 11.2(12)P on a 4700M. WFQ has also been a source of grief in recent 11.2 7200 code - just turn it off. And one can't go back far at all in 11.2 space with PA-2H Rev-B cards that are only just being supported.
Is 11.2(12)P even out yet? I was talking to a Cisco rep, and he said it wasn't out yet. This was last week. This is also for the 7206 platform.

That's what I use throughout my entire network (for the most part) and it works great. I also need that for the POET cards, which are really cool.

We're running 11.2(10a)P on 7206's without apparent errors. However, I am trakcing (hunting?) a problem with one of them - after significant BGP updates, it requires the main routing tabel to be cleared.
