I need some help understanding some things about per-user tunneled node.
In the documentation, i can see that it is required that the user vlan is not tagged (or untagged) in the uplink. But since i have activated the "reserved-vlan" feature, it seems that all traffic from any user will be tunneled using the reserved-vlan, and the final vlan will be set in the final role in the controller. In that case, can i keep the users' final VLAN in the switch's uplink? I have tested it and it works. But is there any downside?
The other question i have is about MTU/Jumbo Frame on the VLANs. Do i need to set the jumbo frame mtu in the reserved-vlan? in the final user's VLAN? or in the switch's uplink vlan (the one it has an ip address)?
When i set it in the user's vlan, or the reserved-vlan nothing changes(user vlan/reserved-vlan is not trunked throughout the network). But when i set the mtu in the uplink vlan, and throughout the network, i can see in the "show tunneled-node-mgr user-tunnel-table" that the mtu is using jumbo frames:
---------------------------------------------------------------------------------------------
#show tunneled-node-mgr user-tunnel-table
Tunnel Info Table Entries
----------------------------------
u - Untagged VLAN
Tunnel Id Tunneled Node BCMC TO UCast Key MTU Curr Users VLANs
--------- ------------- ------------- ---- ---- ---------- -----
tunnel 37 192.168.83.239 1 3 1566 1 1050,4000
tunnel 48 192.168.83.239 1 1 1566 1 1050,4000
tunnel 12 192.168.83.239 1 7 1566 1 1050,4000
tunnel 13 192.168.83.239 1 6 1566 1 1050,4000
---------------------------------------------------------------------------------------------
Is this the right configuration?
I have followed the documentation on ASE to set the jumbo frame parameters:
jumbo max-frame-size 1584
jumbo ip-mtu 1566
Thank you all for the time taken to clarify these things!
Best regards,
