Frame Switch Question

What equipment is recommended for a frame switch?
It seems like quite a few people are using 2500 series but it seems just as expensive to get an 8 port serial mod for a 2610.
What do you guys have set up as your frame switch?

I think “very senior” gets stuck in there because the last six yahoos that applied for the position couldn’t tell a packet from a Snickers bar.
Luck is where opportunity and proper planning meet
I have not failed. I've just found 10,000 ways that won't work.

I have a 2610 currently, I was debating on getting an NM-8A/S and just making it a Frame Switch. I'm trying to determine if thats overkill or not.
I was looking at the specs on the 2520's and I seen this:
2 Serial network interface(s)
2 Low-speed serial(sync/async) network interface(s)
What is the difference between these two port types? I'm used to just seeing Serial network interface(s), I'm just trying to figure out what is the benefit/drawback of the other ports.
You will have to excuse me if this is a dumb question but I'm not that familiar with serial port types. I just want to make sure it's going to be compatible with any WIC's I might purchase or if its something I need to look out for.Cisco Brat Blog

Also, I coincidentally could part with a 2520 or NM-8A/S, so shoot me a PM when you've made a decision, and maybe we can work something out. -
mikej412 Member Posts: 10,086 ■■■■■■■■■■If you're going to compare with the 2520 -- then you should price an NM-4A/S -- I got some for $25 plus shipping.
The 2522 (and 2523 which is Token Ring) have 8A/S plus 2 higher speed Serial ports.
I use an NM-8A/S in a 3620 for my R&S CCIE lab frame relay, a 2523 for my Security lab, and a 2520 over on the Voice side.:mike: Cisco Certifications -- Collect the Entire Set! -

A 2600/2600XM with a NM-4A/S or NM-8A/S will work. The other option is to go for a 2520 or a 2522. A 2521 or 2523 will also work but you have token ring instead of ethernet.
There are async/sync serial WICs as well but they're expensive. -
mgeorge Member Posts: 774 ■■■□□□□□□□If you're gonna build a frame relay switch the 2610 and nm-8a/s is the cheapest route.
You can pick up a NM-8A/S off ebay for under 80 bucks and 2610's are under 30 dollars now for the most part.There is no place like 127.0.0.1 -

see thats the direction I was thinking of going since I already have a 2610. Ive seen some 2520's going for 150+ so it might be the cheaper alternative. plus i can always change the WIC's and do something else.Cisco Brat Blog

sides14 Member Posts: 113Go with the NM-8A/S with either a 2600 or 3600 router. The 2520s are good, but you are limited to 4 ports. If you want to go higher than the CCNA, you will need more than 4 ports.

Panzer919 Member Posts: 462I already have my CCNA, it will be for my CCNP lab. Plus since I have a 2610 all I would need is a nm-8a/s and some memory.Cisco Brat Blog

Setotek Member Posts: 61 ■■□□□□□□□□Does this mean that i can buy a nm-8a/s and stick it into my 2621XM? Can anyone verify? Thanks.

Scroll down to platform support. -
Setotek Member Posts: 61 ■■□□□□□□□□Thanks guys. I guess it would be cheaper to buy this card if you already have a 2600 router rather than buy a 2520 with a 4 or 8 serial port.

Setotek Member Posts: 61 ■■□□□□□□□□Silly Me...Tech Exams has even a cheaper route given you have the equipment...

1x 2520
3 x 2501 with DCE/DTE cables
to combine for a frame relay scenario.
