Service Redundancy Protocol Configuration Mode Commands


Service Redundancy Protocol Configuration Mode Commands
 
 
The Service Redundancy Protocol Mode is used to configure properties for Interchassis Session Recovery services.
 
Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

default
Resets the dead interval to the default setting of 30 seconds.
interval
The amount of time (in seconds) for the dead interval. interval must be an integer from 1 through 65535.
Usage
This command specifies the amount of time that one chassis waits to receive a communication from a peer before the listening chassis determines that the peer chassis is down.
Example
dead-interval 65
 
delay-interval
Configure the delay time, for starting the dead timer, after configuration files are loaded.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
delay-intervalinterval
default delay-interval
default
Sets / Restores default value assigned for specified parameter.
interval
The amount of time (in seconds) for the delay interval. interval must be an integer from 1 through 65535.
Usage
This configures interval for starting the dead timer, after configuration files are loaded.
Example
delay interval 65
 
end
Exits the service recovery mode and returns to the Exec mode.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
end
Usage
Return to the Exec mode.
 
exit
Exits the current configuration mode and returns to the Context Configuration mode.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
exit
Usage
Return to the context configuration mode.
 
hello-interval
Defines the lapse time between sending the hello message.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
hello-interval interval
default hello-interval
default
Resets the hello interval to the default setting of 10 seconds.
interval
The lapse time (in seconds) between sending the hello message. interval must be an integer from 1 through 65535.
Usage
This command configures the hello interval - the amount of time that lapses between the sending of each hello message. Each chassis sends the other chassis a hello message at the expiration of every hello interval.
Example
hello-interval 35
 
monitor authentication probe
Enables the monitoring of the connection between the primary chassis and a specified RADIUS server.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
[ no ] monitor authentication probe context context_name { IPv4_address | IPv6_address } port port_number
no
Turns off the monitoring.
context context_name
Identifies the context being used.
IPv4 _address | IPv6_address
Defines the IP address of the RADIUS server to be monitored.
port port_number
Identifies a specific port for the authentication probe. port_number must be the port for the AAA server.
Usage
This command initiates monitoring of the connection between the primary chassis and the specified AAA server through the use of authentication probe packets. If the connection drops, the standby chassis becomes active.
Example
monitor authentication probe context test1 1.1.1.1 port 1025
 
monitor bgp
Enables monitoring of the connection between the specified BGP peer and the primary chassis.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
[ no ] monitor BGP context context_nameIPv4_address
no
Disables monitoring.
context context_name
Identifies the context being used.
IPv4 _address | IPv6_address
Defines the IP address of the BGP peer to be monitored.
Usage
This command initiates monitoring of the connection between the primary chassis and the specified BGP peer through the use of authentication probe packets. If the connection drops, the standby chassis becomes active.
Example
monitor bgp context test 125.2.1.56
 
peer-ip-address
Specifies the IP address for the peer chassis.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
peer-ip-address { IPv4_address | IPv6_address }
no peer-ip-address
no
Removes the peer IP address of the backup chassis.
IPv4_address | IPv6_address
The IP address of the backup chassis.
Usage
This command is used to identify the peer chassis in the Interchassis Session Recovery configuration. From the primary’s perspective, the peer is the backup and from the backup’s perspective, the peer is the primary.
Example
peer-ip-address 1.1.1.1
 
priority
Sets the initial Interchassis Session Recovery priority of each peer chassis.
 
Important: priority takes affect only during simultaneous initializing of all chassis in an Interchassis Session Recovery configuration, and only if a misconfiguration has both chassis in the same mode (both Primary or both Backup).
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
priority priority_value
default priority
default
Resets the priority to the default setting of 125.
priority_value
The priority for the HA. priority_value must be an integer from 1 through 255.
Usage
This command determines which chassis transitions to the Active state when all chassis have the same mode configuration. priority acts as a tie breaker for the state determination only when all chassis initialize simultaneously. The chassis with the higher priority (higher number) becomes Active while the chassis with the lower priority (lower number) becomes Standby.
Once chassis become operational (after initialization), if there is an event requiring a chassis change of state, then each chassis returns to its previous state (Active or Standby) after both chassis recover.
Example
priority 5
 
route-modifier
Sets the route modifier for the peer chassis.
Product
HA, GGSN
Privilege
Security Administrator, Administrator
Syntax
route-modifier threshold threshold_value
default route-modifier
default
Resets the route modifier to the default setting of 16.
threshold_value
The value that causes the route-modifier counter to be reset to the initial value. threshold_value must be an integer from 2 through 32.
Usage
This command is used to determine when the route modifier should be reset to its initial value to avoid rollover.
Example
route-modifier threshold 10
