CISCO-PORT-TRACK-MIB
This MIB provides configuration for port tracking. Port tracking allows the SAN fabric to recover
quickly from indirect failures on a port. An indirect failure occurs when a connection fails because of a
problem on another link in the path from the port to its remote peer. A direct failure occurs when a link
failure is detected on the local port. Direct failures implement recovery and redundant port failover more
quickly than indirect failures, which are dependent on SAN application timeouts to detect a remote link
failure. To speed up recovery times for indirect failures, this MIB marks critical ports as tracked ports.
Other dependent, or linked, ports can be associated with one or more tracked ports. When a tracked port
fails, all linked ports are shut down, causing an immediate failover to redundant paths.
CISCO-PREFERRED-PATH-MIB
This MIB provides a method of routing traffic over the selected preferred paths, not necessarily the
shortest path, as chosen by routing protocols such as FSPF. This type of control allows you to choose
paths based on characteristics, such as frames received on a selected interface or frames with selected
source FCID. This feature allows you to ensure path separation between switches for different traffic
between a host and a target.
CISCO-PROCESS-MIB
This MIB displays memory and process CPU utilization on Cisco devices. This information should be
used as an estimate only.
CISCO-PSM-MIB
This MIB manages the Port Security Manager (PSM). The PSM consists of two aspects: port binding
and fabric binding. Port binding is concerned with the security of switch ports, and fabric binding is
concerned with the security of the SAN fabric as a whole.
CISCO-PSM-MIB-CAPABILITY
CISCO-PSM-MIB-CAPABILITY provides the implementation details for the CISCO-PSM-MIB, as
implemented in the Cisco MDS NX-OS or SAN-OS.
