SCCP11.9-3-1SR2-1S firmware and Data Vlan problem on 7911 phones
We have updated the firmware of 7911 phones to SCCP11.9-3-1SR2-1S. The case is after update the phones, many user connected to Juniper with LDP switchs have lost the conection on their PC. I mean te phone works but the PC connected to the phone not but it has link.
We have downgrade the phone to previus version (SCCP11.9-0-2SR1S) and their are working now.
I haven't found any bug in this firmware but may be anyone knows what could be the problem.
Mean while we are going to make test with SCCP11.9-3-1SR1-1S version

Unfortunally the SR1 has the same issue.
Is very strange. The users with the problem are connected to a Juniper x3200. This switch is a distribution switch. There is a Cisco 2960 as access swtich connected to the Juniper. The users in the cisco switch work well.
Also, we have others users connected to others x3200 and work fine. The only difference is these Juniper Switches work as Access swiches and the swiches with the problem work as distribution switches conected by fiber to the core and with a Cisco 2960 Access switch conected to them.
Anyone knows which is the most lower firmware we can use for 7911 phones to work in CUCM 9.1 version? becaue all of this is in order to upgrade the CUCM to 7.1 to 9.1 and 9.1 have 9.3.1SR1 firmware.
