polling physical-link

Used for combining multiple physical links into a single engine link.

polling physical-link <name> snmp-agent <agent-name>
 
         interface { <address> | <text> | <index> }
 
         [ bandwidth <mbps> ]
 
         [ passive ]
 
         [ use-64-bit-counter interval-greater-than <seconds> ]
 
no physical-link <name>
 

name--name of physical link

agent-name--name of SNMP agent to be used for obtaining link usage information

address--IP address of the interface, in dotted decimal format (a.b.c.d)

text--value of the interface’s ifDescr MIB variable on the router (maximum length: 255 characters)

index--interface’s ifIndex MIB variable on router (integer in the range 1 through 2,147,483,647)

mbps--maximum capacity (mbps) of the physical link (any non-negative number)

seconds--when present, indicates that a 64-bit counter should only be used for those objects that have a polling interval greater than this (integer in the range 5 through 3600)

Must be in link configuration mode (config-engine-link), which requires privileged-level access.

Once for each physical link.

The polling physical-link command enables you to group physical links into a single engine link. This means that multiple physical links will be polled to determine the link loading for the engine link.

Use the passive keyword for links that the decision maker process cannot control (its link usage will still be used for load optimization. For more information about the load threshold table and the load optimization process, see Chapter 2: WAN Cost and Load Optimization in the CNA Adaptive Path Controller Guide.

Use the bandwidth keyword to specify the maximum physical capacity of a link.

NOTE: Such a link must be declared as a physical link; instead of polling interface, you need to use the polling physical-link command.

When using the use-64-bit-counter keyword, you may also constrain the use of 64-bit counters to only those objects which are polled at a slower interval (specified with the interval-greater-than keyword). This is to work around an update problem exhibited by some router models.

Use the no form of the command to remove the polling configuration from a particular physical link.
