RE: Experience with Directional External Antennas on Cisco

[Rios, Hector J]

The Cisco AIR-ANT2566P4W-R= is an excellent antenna for broad coverage. The 
Cisco AIR-ANT2566D4M-R is also a good option for more focused coverage. You can 
find similar antennas available at a lower cost, with relatively the same specs 
and performance like 
https://www.tessco.com/product/2-4-5ghz-6dbi-dual-polarized-directional-antenna-279467.
 I find that between Ventev and Acceltex you can find just about any antenna 
you need to meet your requirements.

If you have Ekahau, it will have a long list of supported vendor antennas with 
their radiation patterns and you can drop them into a project to see what the 
coverage will look like. Very useful tool.

Re: Cisco 8540 Code Recommendation, Based on Stability?

[Jeffrey D. Sessler]

Note on code.  Cisco does run a very helpful EFT program for their code, and in 
most cases it is supported for production use. It is also supported directly by 
the Wireless BU, which is a plus.  They will post announcements on the Cisco 
community site, and once you’ve signed up, you’ll get future announcements as 
well.  Even if you are not interested in running the code, it’s helpful to see 
what fixes/issues are being addressed in the next MR release.

Here are the current EFT offerings that I’ve aware of.

17.3.4

Subject: [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on Stability?
Hi all,

After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.

Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.

Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Thanks,

Not sure as yet as we have been too busy to get this over to TAC at the moment

We can see that most of our 2801 APs sit at around 30-50% memory utilisation, 
however around 6% of them (about 320) are currently above 60% which is unusual. 
These appear to be climbing steadily at around 3-4% per week as though there is 
a memory leak.
We first spotted this when we got reports from students in a residence saying 
they were connected to wifi but nothing was working. Looking at the AP it was 
sat at 95% memory utilisation. Rebooting the AP restored service. However, we 
then looked at nearby APs and could see them climbing as well. It doesn’t 
appear to be all our APs but some unknown subsection of them.
We only went to 8.10 as we had bought some 9105 APs.

That one’s interesting because it shows affected code is 8.5(140.0), and only

It’s a really annoying bug too as to the user they appear to be connected to 
Wi-Fi but they have no network activity at all. Also the APs seem fine from a 
monitoring perspective unless you are either carefully monitoring their memory 
usage, or they get so far out of memory that they appear to lose their

As such, I really can’t recommend 8.10.151.
