Command History
ModificationRelease
This command was introduced.Cisco IOS XE Everest 16.5.1
Usage Guidelines
A timeout is implemented at the bootloader device prompt, that allows the bootloader to poll the TCP stack
every 200 ms. As a result, the bootloader may take up to 200 ms to respond to pings. However, when the
bootloader is downloading a file, and thus actively polling for new packets, it responds to ping quickly.
Examples
The following is sample output from the ping6 host retries len command:
Device: ping6 2001:dead:beef:cafe::5 6 1000
Ping host 2001:dead:beef:cafe::5, 6 times, 1000 bytes
