To complement Mike's suggestions, make sure you repeat the same command "set vlan egress 1 ge.1.48 tagged" for every vlan you have extended through the cisco switch (i.e. "switchport trunk allow vlan 1,16,32,48,64,80,96,112,120,128,144,200") so that both devices share the same configuration values.
Following is a list of additional commands that might assist you troubleshooting the issue:
->show mac port ge.1.48
->show vlan portinfo port ge.1.48
->show port egress ge.1.48
