In New Version IP-Trunk does not Support PPP and Connection Fails

Publication Date:  2012-07-27 Views:  44 Downloads:  0
Issue Description
Before upgrade the version is VRP3.10-0426sp03 and after upgrade the version is VRP3.10-232112 and IP-Trunk cannot be up.
Alarm Information
The physical state of the interface is up, but the protocol state is down.
Handling Process
1. Check physical interface and it is up. .
2. Check IP-TRUNK interface information and it is found that the link layer protocol of the interface in new version is HDLC, but IP-TRUNK interface of opposite device is PPP protocol.
3. In new version IP-TRUNK interface only supports HDLC protocol. Change opposite device as HDLC and the problem is solved.
Root Cause
1. The physical link is problematic and the interconnection of the packet on protocol layer fails.
2. The protocol of two ports is different and the negotiation cannot succeed.
