dlsw interesting traffic over DDR


To define the dlsw interesting traffic for DDR, we have to methods:

1) access-list 101 permit tcp any eq 2065 any

access-list 101 permit tcp any any eq 2065

2) dialer-list 1 protocol llc2 permit

What is differences between this two defination? any idea please...

Re: dlsw interesting traffic over DDR

Either should be fine to define the interesting traffic. If you have several protocols, and acl might be better.

Re: dlsw interesting traffic over DDR

The "dialer-list 1 protocol llc2 permit" statement is what is used to cause the BRI0 or modem to dial. I assume that under the BRI0 or AUX port there is a dialer-group 1 which links the dialer list to the interface.The other access-list statements permit dlsw peer packets and (2065) is urgent packets.I don't know where the access-list statement is referenced in your config but the little I see llc2 packets will cause a dial out. Once dialed up all traffic will pass and once no more llc2 packets are seen by the dialer-list statement, the idle-timeout timer will start and after that defined period the connection will drop. If you post config I can get more detailed. HTH
