I'm trying to do what seems to be a simple task but cannot get it to work. I've very familiar with the Cisco commands on 2900 all the way up to 6500 series switches. The SG500 has me stumped. I have 3 switches, sw1, sw2, sw3. sw1 and sw2 are stacked. sw3 is standalone and in a different part of the building, maybe 25ft away. All I want to do is set up a trunk port between the stack and the standalone. In going by past experience, I would set the port as :
- switchport mode trunk
- switchport trunk allowed vlan 2,3,4
The SG makes me specify tagged or untagged - which is fine. So any vlan I want to move across the trunk i tag, obviously. I do everything as I've done for years and it doesn't work. VLAN1 is untagged, all VLANs I want to flow are allowed and tagged.
I'm quickly realizing I should have bucked up and just bought what I'm used to but I didn't have a choice in the matter.
Any help would be great!
