dlsw interesting traffic over DDR

[fujin.huang]

Hello,

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...

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

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
