Brocade Virtual ADX MIB Reference 11
53-1003312-01
RFC 2863: The interfaces group MIB
RFC 2863: The interfaces group MIB
RFC 2863 is supported on the Virtual ADX devices.
IfIndex assignment persistance
The following interfaces on the devices have ifIndex assignment that are persistent across reboots
and switchover operations:
• Physical ports
• Virtual ports
• Loopback ports
NOTE
The ifIndex should be derived from the snIfIndexLookupTable using the InterfaceId (in OID form),
instead of assuming that the ifIndex to always stay persistent across reloads.
On the following interfaces, IfIndex assignments are not persistent across reboots and switchover
operations:
• MPLS tunnel interfaces
• Trunk ports
ifType for interfaces
On the devices, ifType for all Ethernet interfaces (10/100/1G/10G) returns the value
ethernetCsmacd(6) as mandated by RFC 2665. This behavior is not supported on Brocade Virtual
ADX devices.
Statistics for virtual routing interfaces
The ifTable and ifXTable display information for switched and routed packets on virtual routing
interface are installed. The extended-counter routed-switched command must be configured to
enable separate accounting of routed and switched packets on virtual routing interfaces.
ifTable attributes
The following MIB attributes of the ifTable return information for switched and routed packets.
MIB attribute Information attribute returns
ifInOctets Total Rx bytes in this virtual routing interface
(32 bit counter)
ifOutOctets Total Tx bytes in this virtual routing interface
(32 bit counter)
ifInUcastPkts Total Rx packets in this virtual routing interface
(32 bit counter)
ifOutUcastPkts Total Tx packets in this virtual routing interface
(32 bit counter)
ifInNUcastPkts Always returns 0
