[c-nsp] RSPAN and 3550

[Alexey Luckyanchikov]

I need to setup RSPAN session between two 3550. Network topology:
+------+ GigaStack +------+ LX/LH +------+ GigaStack +------+
|3550-1|-----------|3508-1|-------|3508-2|-----------|3550-2|
+------+           +------+       +------+           +------+

3550-1 and 3550-2 are in vtp transparent mode, all 3508 - in separate
vtp domain (server and client).

3550-1 configured as RSPAN source, 3550-2 - as RSPAN destination. I
see packets on reflector port, but 3550-1 does not transmit any
packets in RSPAN vlan to 3508-1:
3508-1#sh mac-address-table int gi0/5 vlan 107

3508-1#

vlan 107 allowed on trunk between 3550-1 and 3508-1, all switches have
vlan 107 in their vlan databases.
Any suggestions how to fix this issue?

3550-1 configuration:
vlan 107
