PPPoE Interface don´t reconnect - VE R80.40

Hello all,

I have a PPPoE interface attached to a eth0 in a VE environment (VMWare).

 

After a modem hangup, this pppoe interface lease his IP address and stop to communicate.

I need to login in gateway Web page, go to interfaces, edit the pppoe interface and set to off, save and set to on again.

Only after this, I have communication again on this interface.

 

So, there is a command, or a job to do this OFF, ON automatically when this interfaces losing communication?

There is any command to avoid this hangup?

 

Here are the logs from /var/messages when Modem hangup and when I put OFF / ON the interface.

Hello,

  I am able to also replicate this issue on my 3200 appliance running R80.40 with JHF Take 78.  On my PPPoE interface when the lease expires I get the following logs in my /var/log/messages.log file...

Sep 24 09:31:03 2020 Als-Home-GW pppd[5089]: LCP terminated by peer (connect time expired)
Sep 24 09:31:03 2020 Als-Home-GW pppd[5089]: Connect time 10079.7 minutes.

Sep 24 09:31:03 2020 Als-Home-GW pppd[5089]: Modem hangup
Sep 24 09:31:03 2020 Als-Home-GW pppd[5089]: Connection terminated.
Sep 24 09:31:03 2020 Als-Home-GW pppd[5089]: Failed to disconnect PPPoE socket: 114 Operation already in progress
Sep 24 09:31:03 2020 Als-Home-GW pppd[5089]: Exit.

The log entry shows that the gateway is clearly unable to properly disconnect the PPPoE socket.  At this point manual intervention is required to properly disconnect the PPPoE socket and ultimately allow the LCP connection to reestablish.  Usually simply cycling the up/down state of the PPPoE interface resolves the issue.

This definitely appears to be a bug and as such, I would open a support case with TAC.  I'll also open a case and update this forum accordingly.

As a work around I was able to create a script that will bounce the interface.  Then use Job scheduler to run the script daily at a specific time...

Step 1 - Login to the gateway via SSH in expert mode and create the script in the scripts directory...

vi  /opt/CPsuite-R80.40/fw1/scripts/bounce_interface_pppoe1.sh

contents of the script should be...

#!/bin/sh
# This script is used to bounce an interface.

clish -c "lock database override"
clish -c "set interface pppoe1 state off"
clish -c "set interface pppoe1 state on"

Step 2 - Make the script executable...

chmod 777 /opt/CPsuite-R80.40/fw1/scripts/bounce_interface_pppoe1.sh

Step 3 - Log into the gateway via the Gaia GUI and create the scheduled job that will reference the script...

Step 4 - Verify that its working by checking the /var/log/messages file and grep for pppd logs.

Hello Allen,

Thanks for your reply.

Sorry for not reply earlier.

As a workaround, I created a daily job that put interface down, wait for 30 seconds and set interface up again.

This reset the PPPoE connection timeout.

It´s very similar that your last post.

Thanks again.

[Expert@gwckp01:0]# cat pppoe.sh
#!/bin/sh

clish -c "lock database override"
clish -c "set interface pppoe1 state off"
sleep 30
clish -c "set interface pppoe1 state on"
