SwtichPort Access vs General
I need some advice in making a config change to a Port-Channel that is currently setup in Access Mode. This network was setup by another Network Admin before my Company Acquired them. Let me explain to the best I can how the current Setup is.....
- Switch 1 (N Series)
- Vlans 10,20,30,40,50
- Port Channel 1 is Access Vlan 50 (Connects to Switch 2)
- IP routes to Vlan 60 over Vlan 50
- Switch 2 (S Series)
- VLAN 60
- Port Channel 1 Access Port IP in Vlan 5
- Default IP Route over Po1's IP
I created a new VLAN 80 on Switch 1 and 2. However, it does not route because there is no Patch for this VLAN between the Switches. If I change Po1 on Switch 1 to a General Switchport and make VLAN 50 its pvid and allow Tagged VLAN 80 over will this cause any issues? I also will need to make a change to Switch 2 PO1 allowing VLAN 80 over it too. The only other option is to create an Access VLAN 80 Port Channel on each Switch and connect them.
No Events found!

VieiraR,
If you want VLAN 80 to pass as tagged traffic then yes you will need to make sure that VLAN 80- exist on both switches and then general mode with "switchport general allowed vlan add 80 tagged"
On the S-series if it is:
OS9 then you'll need to add port-channel 1 as tagged for VLAN 80
OS10 then switchport mode trunk with command "switchport trunk allow vlan 80"

This is what I felt would need to be done. Yes the S Series is on OS9 we have no updated to OS10 yet. On the next maintenance schedule I will make the change to the Port-Channels to pass the new VLAN. Thanks for the confirmation
