actually the topology on the core is configured with 2 switch cisco core A,B with 2 etherchannel for back to back connection and with 16 EtherChannel vs the access switches configured with mode on and PAgp (8 etherchannel on core switch A vs the access switches and 8 etherchannel on core switch B vs the access switches).
On the cisco docs about the VSS I found the feature "Multichassis EtherChannels" (LACP 1:1 Redundancy / Enhanced PAgP / BFD) but as I can't utilize this feature on access switches vs the new core VSS how proceed (the feature needs to be enabled at both ends of the link? ) ?
FOR Enhanced PAgP:
For dual-active detection to operate successfully, one or more of the connected switches needs to be able
to process the new TLV. Catalyst 6500 series switches with Supervisor Engine 32 and Supervisor Engine
720 have this capability, if they are running Cisco IOS software release 12.2(33)SXH1 or later. For a list
of other Cisco products that support enhanced PAgP, refer to Release Notes for Cisco IOS Release
12.2(33)SXH and Later Releases.
Can I configure the standard etherchannel on the VSS vs the access siwtches ?
Witht this 'standard' configuration I lost only the 'Dual-Active Detection' feature on the access switches ?
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
