I have Nortel ERS-5520 at remote site with voice and data VLAN's. 5520 is used as Layer 3 switch connected to provider's WAN router through routable VLAN link. I was told that I need to tag WAN packets with Diffserv (DSCP) and shape the traffic on the ingreess. I was looking at some QoS commands...

elgrandeperro Where is that startup script? Are you talking about logon script or is that something else. Thanks

motoslide Yes, it can telnet to itself. I was looking at SCO web site and their knowledge base is recomending to check this: Check the permissions for rlogin under /usr/bin. The permissions should look like this: -rws--x--x 1 root bin rlogin ^...

mando1 There is no option to create a trunk port on the BES1020. What they mean that you enable egrees tagging on the ports and make one of the them a trunk port. This is what I do on my BES1020 site: I've defined two vlan's, lets say VLAN 100 data VLAN 101 voice all ports are members of data...

mando1 I have BES1020 in my site and it is working fine. Did you enable egrees tagging on BES1020 ports to support multiple VLAN id's? You need to setup a trunk port on BES1020 to your 5520 or core switch and create subinterfaces with dot1q enabled for each vlan created on BES1020. Make sure...
