ios advice before purchase

hi I currently have the following:

cisco 2950 layer 2 -

c2950-i6q4l2-mz.121-19.EA1c.bin - currently installed
c2950-i6k2l2q4-mz.121-22.EA4.bin

cisco 3550 layer 3 -

c3550-i5q3l2-mz.121-22.EA2.bin - currently installed
c3550-ipbase-mz.122-25.SEB4.bin

question 1. ive also seen: ipservices ios type also and I assume there are others but not sure if 'emi' has more features ?

question 2. I know that 'smi' is for layer 2 but not sure if that is what my above cisco 2950 is currently using ?

question 3. I know that 'emi' is for layer 3 but not sure if that is what my above cisco 3550 is currently using ?

Please post the output of a "show version".

hi don, apologies for not getting back asap.

- I have attached individual screenshots of sh version - 3 x 2950 switches which allow 2 2950 for 64 vlans & 1 with 250 vlans allowed

- I have attached the 1 x 3500 sh version also

my cisco 2950 does not allow any of the below with current ios: - (expected)

- vlan access-maps
- sso & nsf for eigrp & ospf or either
- switchport autostate exclude
- multicasting routing
- ssh 1024 or higher

I attempted to check the below configurations on the below but not all work ?

cisco 3550:

- vlan access-maps - allowed
- sso & nsf for eigrp & ospf - not features
- switchport autostate exclude - no features
- multicating-routing - allowed
- ssh 1024 or higher - no features

I was going to purchase a specific cheap emi 3550 from ebay but phone to confirm so that I can at least check practical config I need to do.

q1. what you think as I also wish to configure: 2 x 3550 & 2 x 2950 in sso/cef & eigrp or ospf for example to understand practically how 'fib & adj' functions practically in cef, although yes I can read and understand but want to see the fault tolerance being carried out ?

...just like I can see with my 'vtp server (primary & secondary) connected to an 'access switch'which I have already tested

Okay. Looks like you didn't have ip routing enabled.

Not sure why you're using sso and redundancy commands. This isn't a modular, dual supervisor platform.

ASKER

yes I did the configs shown are show what features were not available is what I mean

ASKER

oh yeh you are right I am not using a 6500 for eg

hi don, is it ok if I return to this question tomorrow!

I have not enable 'pim' on an interface as did not know. I will check.

if I wish to 'exclude autostate' - I assume this be allowed if required on another switch or different ios.
