SNMP MIB M
ANAGEMENT
6-8
Interface Administration
Data for this window is extracted from the Interface Group
in MIB II (RFC 1213). Each MAC frame type supported by a
physical network interface is listed as a unique logical
network interface in the display window. (Refer to ifType in
RFC 1156.) For example, even though there may only by one
physical network interface on a monitored device, it may
concurrently support both ethernet-csmacd and
iso88023-csmacd. Also note that the same type may be
reported more than once where a logical interface includes
several valid subtypes. For example, ethernet-802.2 and
ethernet-II both fall under ethernet-csmacd.
