I'm working on a project for a client that has 5 4507Rs & a 6506 switche. There are 3 total VLANS (1-3). Each 4500 has 3-48 port FE blades, each spilt in half;24 to VLAN2 the other 24 to VLAN3. I have setup GB trunks from the 6500 to the 4500s. I can ping the VLAN IPs from any of the switches, but I can not seem to pass traffic from one switch to another, dispite what VLAN I try. ANy thoughts?
I'm assuming you have created layer 3 definitions on at least one of your boxes , you can not pass traffic between vlans without a router . Make sure you have a routing protocol setup with the appropriate network statments to go along with it .
I found the issue with the traffic not being passed between switches. This command: spanning-tree uplinkfast max-update-rate 15 was causing my issue. However, not being an expert, my understanding of that command was to speed up convergence if one of my 2 uplinks went down. Here is the config for the 4500:
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
boot system bootflash:cat4000-i9s-mz.121-19.EW1.bin
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
