What is supervisor engine in Cisco 6509?
Supervisor Engine is a module that is installed in the Cisco Chassis-based Catalyst Switches or Routers. Supervisor engine contains nearly all the same components of a fixed Cisco Switches or Routers.
What is a Cisco switch supervisor?
The supervisor module is the module that is the brains behind the whole switching operations. Its usually found in chassis based switches, nowadays, it handles everything, including routing and switching (older models had them separated.)
In which redundancy mode switch modules will be reloaded before the standby router initialize the supervisor functions?
You can use the following redundancy modes on Catalyst switches: Route Processor Redundancy (RPR)—The redundant supervisor is only partially booted and initialized. When the active module fails, the standby module must reload every other module in the switch and then initialize all the supervisor functions.
What is redundancy mode SSO?
SSO HSRP alters the behavior of HSRP when a device with redundant Route Processors (RPs) is configured for stateful switchover (SSO) redundancy mode. When an RP is active and the other RP is standby, SSO enables the standby RP to take over if the active RP fails.
Can we do load balancing in HSRP?
Thus, HSRP provides Layer-3 redundancy, but no inherent load balancing.
What is RPR mode?
During RPR mode operation, the startup-config files and the config-register configurations are synchronized by default between the two supervisor engines. In a switchover, the new active supervisor engine uses the current configuration. Default Settings for RPR.
What is Layer 3 redundancy?
When the router that is the default gateway goes down, or the physical path to the router, your machine no longer has a default gateway. Even if there is another router present on that network segment, its information does not match what the user’s machine is assigned. This is where layer 3 redundancy comes in.
What is SSO mode in Cisco?
The SSO HSRP feature enables the Cisco IOS HSRP subsystem software to detect that a standby RP is installed and the system is configured in SSO redundancy mode. Further, if the active RP fails, no change occurs to the HSRP group itself and traffic continues to be forwarded through the current active gateway device.
