Having issues setting up IP routing on 4526t-pwr
« on: December 17, 2016, 10:42:50 PM »
I'm working on experimenting with subnetting and L3 routing.  Here is my scenario:

I've got a server and a standard pc.  Both running windows.  The PC is running 7 with an IP Address of 10.30.0.2 with the default gateway being set to 10.30.0.1 and the Server is 2008 with an ip of 10.10.0.2 with the default gateway being 10.10.0.1. 

On the switch I've got two Vlans set to the correct ports on the switch.  I've enabled ip routing on all of the vlans and made sure that tagging was set to untagged. 

The issue I'm getting is I can't ping the default gateway on the PCs.  However, I can ping the default gateways on the switch.  If I attempt to look at the routing table, I will only see 10.10.0.1 on the table, not 10.10.0.2.  Same for the Arp table as well. 

Am I missing something here?  Any information you need let me know, I'm kind of running off of memory as I haven't played with this in a few weeks since starting a new job. 

Thank you for your help.

I could only get it in as an attachment...it kept telling me that I'm not allowed to post external links. 

I'm starting to think that it could be a licensing issue.  Which would be a shame.

ok, here you go:



MLT - your MLT is NOT enable, therefore not acting as an MLT - pls see my recommendations below:

mlt 1 name "Test" enable member 3,14,24 learning disable




BPDU-Filtering - is enabled on ALL your interfaces, that needs to changed to User-Ports ONLY, additional I'd recommend to activate SLPP_Guard in Parallel to BPDU-Filtering:

interface FastEthernet ALL
spanning-tree bpdu-filtering port "NonMLT-Links" enable timeout 120
exit

interface "NonMLT-Links"
slpp-guard enable timeout 120
exit




Mgmt - Vlan:
Make sense to declare on of your Vlans (not Default Vlan) das Mgmt-Vlan:

mgmt vlan 20 (or) 30


RIP: Rip is enabled on both Vlans - you have to use RIP?

Btw. most of your issues should be reported in your local logfile:

show log sort-reverse

Good luck   ;)

Thank you so much for your suggestion.  I appreciate the response!

I got the MLT command to work...though I lost access to my telnet session.  I made port 24, which was my mgmt vlan,  part of all three vlans.   Might not have been the best way to go I'm assuming? 

I enabled RIP as a last resort thing.  I was out of ideas. This config is such a mess, I should just scrap it and start all over.

So I did your show log sort-reverse.  Seems that I do have an expired license.  Says "ECMP features disabled due to inadequate license." 

Any idea on how I could perhaps acquire one for education purposes?  Or how I can play with a switch that would grant me all access that would not require a subscription?
