Timer Worksheet

CCNP SWITCH will test one’s knowledge on timers of various protocols. I assembled a worksheet to help with learning the timers which are likely on the test. If a protocol or timer is missing or incorrect, please let me know in the comments. Timers are included relating to the following protocols:

• Spanning Tree
• Rapid Spanning Tree
• HSRP
• VRRP
• GLBP
• UDLD
• DTP
• VTP
• PAgP

Update: I have updated the timer worksheet to include another UDLD timer and Errdisable defaults.
