Catalyst 6509 Vlan speed issue

[lukebrennan]

Hi Guys,

I'm new here, and have a question to get things rolling:

I recently setup a new user and managment vlan on my network which has been up until this point running all on vlan 1. The problem is I cannot download data at over 9mB/sec from an end device, uploading on this vlan is fine, up to 30mB/sec. At first I thought it was a limitation of a new 3750 I was using (maybe fiber issue), but after configuring a gigabit port directly on our 6509 core to this new vlan the same issue exists. I will note that devices on vlan 1 do not have this problem. I am kind of stumped here, the ports are connected at full duplex gig. The following is my vlan configuration on the 6509 core switch ( I have removed addressing from my paste, sorry) and a trunk port used for my access switch. Any help or direction is appreciated:

vlan 500

name Managment-Test

!

vlan 503

name User-Test

interface Vlan500

description Managment - Test

ip address *.*.*.78 255.255.255.240

no ip redirects

no ip proxy-arp

load-interval 30

interface Vlan503

description Access -Test

ip address *.*.*.254 255.255.255.0

no ip proxy-arp

load-interval 30

nterface GigabitEthernet7/22

udld port aggressive

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 500

switchport trunk allowed vlan 1,500,503

switchport mode trunk

Sorry, cef needs to be capitalized, alternatively remove the include statement and just make sure that you seee something similar to the following:

IP CEF switching is enabled

IP Normal CEF switching turbo vector

IP route-cache flags are Fast, CEF

It appears cef is working I'm not sure why you're not getting full speed between vlans. I'll research this more and post back here if I find anything.

Gateway of last resort is *.*.160.1 to network 0.0.0.0

*.*.0.0/21 is subnetted, 1 subnets

C *.*.*.0 is directly connected, Vlan1

10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C *.*.159.64/28 is directly connected, Vlan500

C *.*.128.0/24 is directly connected, Vlan503

S* 0.0.0.0/0 [1/0] via *.*.160.1

Thanks gearnsc, i'm not going to open a tac ticket for a few more days.

One thing I havn't tried is creating a couple different vlans and trying, shouldn't matter but doesn't hurt to see I guess.
