Packets with the VLAN Priority Tag

Please note the following:

1. The OSM/ESM

does not

support packets with VLAN tags according to IEEE

802.1Q. Configure your network so that no packets with VLAN tags are

transmitted via the OSM/ESM.

2. Your network should be designed so that no packets with a priority tag and a

priority higher than 3 (IEEE 802.1p) are transmitted via the OSM/ESM since these

packets can influence redundancy functions (for example, longer switchover times

if a fault develops).
