Recommendations

Info

• Upstream device Must be in trunk mode (eg: switchport mode dynamic desirable) • Client side interface changes Client side changes intf to trunk Client side does not change access/native vlan id; remains vlan 1 Client adds mgmt vlan (eg: 80) to allowed vlans list on trunk • Table below showing upstream switch intf config scenario Table assumes smart install management /startup not vlan 1 Eg: vlan 80 is startup vlan configured on Director Remove vlan 1 from trunks to clients Si Director Gig 2/2 mode: trunk Native: Vlan 4000 Allowed: vlan 80 Gig 0/1 mode: auto Native: Vlan 1 Allowed: vlan 80 Client Upstream Switch Interface config; smart install mgmt vlan is 80 Acces s/ Trunk Native vlan id Trunk 4000 Trunk 1 Vlan 1 allowed on trunk yes yes Client side Smart Install works? Works Works; comments Trunk created; vlan 80 is added to allowed list Trunk created; vlan 80 added to allowed list even with Vlan 1 allowed on upstream link Trunk 80 no No client cannot change the native vlan ID © 2011 Cisco and/or its affiliates.

VLAN 4093 is Smart Install VLAN !! switchport trunk native vlan 4001 switchport trunk allowed vlan 2-17,4093 switchport mode trunk • Configuration changes applicable to physical ports as well • With new configuration, the client switch negotiates the mode to ‘access’ and gets IP on the access vlan • Smart Install works as before without vlan 1 being enabled on the Director and other switches • Tested SBA and UAG TME labs. © 2011 Cisco and/or its affiliates.
