The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS Enhanced Interior Gateway Routing Protocol (EIGRP) commands that begin with T.
To adjust the Enhanced Interior Gateway Routing Protocol (EIGRP) time limit for the active state, use the timers active-time command. To disable this function, use the no form of the command.
timers active-time [time-limit | disabled]
no timers active-time
Disabled
Address family configuration mode
Router configuration mode
Router VRF configuration mode
|

---|---|
5.0(3)N1(1) |
This command was introduced. |
Use the timers active-time command to control the time that the router waits (after a query is sent) before declaring the route to be in the stuck in active (SIA) state.
This command requires the LAN Base Services license.
This example shows how to configure an indefinite routing wait time on the specified EIGRP route:
switch(config)# router eigrp 1
switch(config-router) address-family ipv4 unicast
switch(config-router-af)# timers active-time disabled
switch(config-router-af)#

copy running-config startup-config |

show ip eigrp |

To adjust the time limit for nonstop forwarding (NSF) convergence for the Enhanced Interior Gateway Routing Protocol (EIGRP), use the timers nsf converge command. To disable this function, use the no form of the command.
timers nsf converge seconds
no timers nsf converge
seconds |
Time limit for convergence after an NSF switchover (in seconds). The range is from 60 to 180 seconds. The default value is 120. |

5.0(3)N1(1) |
This command was introduced. |
Use the timers nsf converge command to control the time that the router waits for convergence after a switchover.
This command requires the LAN Base Services license.
This example shows how to configure the NSF convergence time for EIGRP:
switch(config)# router eigrp 1
switch(config-router) address-family ipv4 unicast
switch(config-router-af)# timers nsf converge 100
switch(config-router-af)#

show ip eigrp |
Displays EIGRP information. |
To set the timer that determines how long an NSF-aware Enhanced Interior Gateway Routing Protocol (EIGRP) router holds routes for an inactive peer, use the timers nsf route-hold command. To return the route hold timer to the default value, use the no form of this command.
timers nsf route-hold seconds
no timers nsf route-hold
seconds |
Time, in seconds, that EIGRP holds routes for an inactive peer. The range is from 20 to 300 seconds. The default is 240. |
EIGRP NSF awareness is enabled.

5.0(3)N1(1) |
This command was introduced. |
Use the timers nsf route-hold command to set the maximum period of time that the NSF-aware router holds known routes for an NSF-capable neighbor during a switchover operation or a well-known failure condition. The route hold timer is configurable so that you can tune network performance and avoid undesired effects, such as "black holing" routes (advertising invalid routes) if the switchover operation takes too much time. When this timer expires, the NSF-aware router scans the topology table and discards any stale routes, allowing EIGRP peers to find alternate routes instead of waiting during a long switchover operation.
This command requires the LAN Base Services license.
This example shows how to set the route hold timer value for an NSF-aware router to 2 minutes (120 seconds):
switch(config)# router eigrp 1
switch(config-router) address-family ipv4 unicast
switch(config-router-af)# timers nsf route-hold 120

To set the time limit to signal a nonstop forwarding (NSF) restart for the Enhanced Interior Gateway Routing Protocol (EIGRP), use the timers nsf signal command. To return the route hold timer to the default, use the no form of this command.
timers nsf signal seconds
no timers nsf signal

Time, in seconds, that EIGRP waits for a peer to signal an NSF restart. The range is from 10 to 360 seconds. |

This command was introduced. |
Use the timers nsf signal command to set the maximum period of time that the NSF-aware router waits for an NSF-capable neighbor to signal a restart.
This command requires the LAN Base Services license.
This example shows how to set the signal timer value for an NSF-aware router to the maximum (30 seconds):
switch(config)# router eigrp 1
switch(config-router) address-family ipv4 unicast
switch(config-router-af)# timers nsf signal 30
switch(config-router-af)#
