What’s the default CDP holdtime in seconds for Cisco routers?
Answer Posted / shahin07
By default, the CDP advertisements are sending after every
60 seconds with a hold time value of 180 seconds.
You can change the default configuration by these set of
commands:
Router # configure terminal
Router (config) # cdp timer 30
Router (config) # cdp hold time 90
Router # show cdp
You can configure the CDP timer value from 5 to 254 seconds
and CDP hold time value from 10 to 255 seconds.
