What does a supervisor engine do?

What does a supervisor engine do?

Benefits of Supervisor Engines The supervisor engine contains the following integrated daughter cards that perform forwarding and routing and provide the protocols supported on the router.

Which is the redundancy operating mode in Cisco?

Answer: In software, supervisor engine redundancy is enabled by running the redundant supervisor engine in route processor redundancy (RPR) or stateful switchover (SSO) operating mode.

What is RPR redundancy?

• In route processor redundancy (RPR) redundancy mode, the ports on a supervisor engine in standby. mode are disabled. • RPR supports IPv6 multicast traffic.

What is non stop forwarding?

Cisco Nonstop Forwarding (NSF) works with the Stateful Switchover (SSO) feature to minimize the amount of time a network is unavailable to users following a switchover. The main objective of NSF SSO is to continue forwarding IP packets following a Route Processor (RP) switchover.

What is SUP switch?

The supervisor engine is the central forwading intelligence of a modular switch such as the 4500 and 6500 series, and also takes care of the control plane and other functions. Think of it as the “brains” of your switch.

What is supervisor engine in Nexus?

The Cisco Nexus 7000 Series Supervisor Module is designed to deliver scalable control plane and management functions for the Cisco Nexus 7000 Series chassis. It is based on a dual core processor that scales the control plane by harnessing the flexibility and power of the dual cores.

What is redundancy mode?

Redundant Mode gives you super-reliable internet by sending all of your data over both the cellular and Wi-Fi connections. It uses a lot of data and a lot of battery power, so it’s not recommended for normal usage. It’s more appropriate for protecting very important sessions.

What is RPR mode in VSS?

The Catalyst 4500 and 6500 series of switches do provide options for redundant Supervisor Engines. Switches can run multiple route processors (supervisors) in 3 modes: RPR (Route Processor Redundancy) RPR+ (Route Processor Redundancy plus) SSO (Stateful Switchover)

What is GR in network?

There are number of terms we use in today’s High Availability Network like NSF (Non-Stop Forwarding), GR (Graceful Restart) and NSR (Non-Stop Routing).

What is NSR in networking?

Nonstop active routing (NSR) uses the same infrastructure as graceful Routing Engine switchover (GRES) to preserve interface and kernel information. However, NSR also saves routing protocol information by running the routing protocol process (rpd) on the backup Routing Engine.
