Free CCNP SWITCH Video Boot Camp: HSRP And Security

Explore hsrp fundamentals and perform the first lab to configure a virtual router, establish active and standby routers, and verify with show standby group details.

Explore how HSRP elects the active router using priority, verify with pings on the virtual router, and enable preemption to ensure the highest priority device becomes active.

Learn how hsrp transitions from init to active, set up multiple groups with virtual router IPs to balance load between switches, and configure active/standby roles for traffic distribution.

Explore HSRP interface tracking, adjusting priority with track objects to promote preemption and seamless failover between active and standby routers while monitoring interface status and line protocol changes.

Learn to configure HSRP timers, including hello and hold times, and implement md5 authentication with key strings or key chains, plus password encryption for security.

Explore port security on Cisco switches, configuring per-port secure MAC addresses, violation modes, and aging options; enable, verify with show commands, and work with static, dynamic, and sticky MAC addresses.

Set the port security maximum to three on fast ethernet 0/2, configure two static MACs, and observe the next learned address becoming a dynamic secure entry.

Explore aging concepts for MAC address tables and port security, including static aging, absolute and inactivity aging, and set dynamic entries to 300 seconds (5 minutes), then verify with age.

Demonstrate how a port enters error disable mode after a port security violation. Show how error disable recovery restores the interface with a configurable timer and maximum MAC addresses.
