VLAN interface index
The interface index of a VLAN is computed using the following formula:
ifIndex = 2048 + VLAN multicast group ID (MGID)
Because the default VLAN always uses an MGID value of 1, its interface index is always 2049.
MLT interface index
The interface index of a multilink trunk (MLT) is computed using the following formula:
ifIndex = 6143 + MLT ID number
MAC address assignment
You must understand MAC addresses assignment if you perform one of the following actions:
Define static Address Resolution Protocol (ARP) entries for IP addresses in the switch
Use a network analyzer to decode network traffic
Each chassis is assigned a base of 1024 MAC addresses. The first 256 are reserved for ports and
other internal purposes. Routable VLAN start at an offset of 256 and above.a
