threshold-monitor nexthop

Configures the monitoring the utilization of the Next Hop Table or the Encap Table depending on the platform. The current values of number of next hop entries (in %) is compared with the configured profile limits and against the available hardware space. An alarm is raised when the number of next hop entries falls below the configured low threshold or exceeds the configured high threshold.

Syntax

threshold-monitor nexthop { [ high-limit value-in-percentage | low-limit value-in-percentage | [ actions [ all | none | raslog | snmp ] ] ] }

no threshold-monitor nexthop { high-limit | low-limit | actions }

Parameters

high-limit value-in-percentage

Specifies the high usage limit as a percentage (%) of available Next Hop table resources that will trigger the configured action. The range is 10%-100%. The default value is 90%.

low-limit value-in-percentage

Specifies the low usage limit as a percentage (%) of available Next Hop table resources that will trigger the configured action. The range is 10%-99%. The default value is 70%.

actions

Specifies the action to be taken when a threshold is exceeded. The values supported are all, none, raslog, and snmp. The default action is all.

all: RASLOG and SNMP trap will be sent when the threshold is exceeded. This is the default configuration.
none: No action will be taken when the threshold is exceeded.
raslog: Only RASLOG will be sent when the threshold is exceeded.
snmp: Only SNMP traps will be sent when the threshold is exceeded.

Modes

Global Configuration Mode

Usage Guidelines

The no form of this command will reset the values to default.

The low-limit threshold value cannot be equal to or higher than the value configured for the high-limit threshold value.

For the hardware tables that share space, it is possible to run out of free space even when the number of next hop entires has not reached its configured maximum. Once the shared hardware space runs out, addition of new IPv4 Route/IPv6 Route/ARP/ Neighbor Discovery/Nexthop entries will be affected.

Examples

The following example configures the lower and higher threshold monitoring values for the Next Hop table.

SLX# configure terminal
SLX (config)# threshold-monitor nexthop high-limit 95 low-limit 50 action all
SLX (config)#

The following example resets the configured Next Hop table threshold monitoring values to their defaults

 SLX# configure terminal
SLX (config)# no threshold-monitor nexthop high-limit
SLX (config)# no threshold-monitor nexthop low-limit
SLX (config)# no threshold-monitor nexthop action
