Cisco 4900 and VRRP

came across configs for a 2960 stack that are connected to a 4900 with 10gbe. i know the switches have a couple differnet vlans assigned to them, but i don't see the membership represented in the switch config, but i do see it on the 4900 which is routing the vlans, can someone explain how that works?  i am attaching the configs.

thanks

You're correct. There don't appear to be any ports on the 2960 stack that aren't in VLAN 1.

But there are two links on the 2960 stack that are configured as trunks (which carry all VLANs).  One of which is connected to 4900-1.

And there could also be others.

so i would still have to assign vlan membership to the ports? it doesn't get it from the 4900?
Don JohnstonInstructorCommented:
No. Which ports are members of what VLAN's is defined on the switch.
