Slow l2tpv3 pseudowire, low bandwith

ciscocase

Hello,

 

i've configured a pseudowire-connection between two cisco 2811, to use some vlans on an other site. Connection works but i can only use 10% of the actual Bandwith. Something seems to slow down the pseudowire connection. Here's the related configuration:

 

Site1:

pseudowire-class wire1
 encapsulation l2tpv3
 protocol none
 ip local interface FastEthernet0/0

 

interface FastEthernet0/1
 no ip address
 duplex auto
 speed auto
 xconnect 172.20.1.210 1 encapsulation l2tpv3 manual pw-class wire1
  l2tp id 222 111
  l2tp cookie local 4 54321
  l2tp cookie remote 4 12345
  l2tp hello l2tp-defaults

 

Site2:

pseudowire-class wire1
 encapsulation l2tpv3
 protocol none
 ip local interface FastEthernet0/0

 

interface FastEthernet0/1
 no ip address
 duplex auto
 speed auto
 no cdp enable
 xconnect 172.16.1.210 1 encapsulation l2tpv3 manual pw-class wire1
  l2tp id 111 222
  l2tp cookie local 4 12345
  l2tp cookie remote 4 54321
  l2tp hello l2tp-defaults

 

Between the two location there is a leased line with 50mbit troughput, but over the pseudowire, speed seems limited to 5Mbit. Any Ideas whats slowing down the l2tp connection?

 

Please forgive my poor english.

Found it, there was a rate-limit, i've overseen.

Neat, but also keep in mind, 2811s are a bit light weight if you really want to push 50 Mbps duplex.

Also, with l2tpv3, you may have fragmentation which can slow your transfer rate too.

Hi, how did you remove the rate limit ? what configuration you did, i have the same issue

Hi, how did you disabled the rate-limit? What configuration you applied? I have the same issue here

I put that rate-limit to an interface years ago, to reduce traffic fom 10Mbit to 5Mbit. Then the connection was not used anymore. Nowadays someone needed a VLAN in an other location so, I activatet the connection. But in the meantime, the service provider  speed up the leased line to 50Mbit, but over my pseudovire, there was still my rate-limit active. 

 

interface FastEthernet0/0
rate-limit output 35000000 5000000 10000000 conform-action continue exceed-action drop

 

Now it's looks like that, so 35Mbit can be used. But if you did not configure a rate-limit like this, it'll not help you.  

No rate limit in my case but any thanks for your clarification.
