times are well within ping limits.

Workaround
None required.
The software recognizes if the group name is
alphanumeric, however it will not work when
the name of the group is numeric (for example
2, 3, etc.).
User can configure the same TACACS user
locally and use LOCAL authentication method
for HTTP. The user will be able to get access
based on the local user access level (Read-write
or Read-only).
Administrators can ping the TFTP server from
the switch. Administrators should ensure the
TFTP server is available, the requested file is
available, and the permissions are set correctly.
Utilize the show stack-port command to
identify stack port configuration issues.
Configure the acct-port to the default using the
acct-port 1813 command in Radius accounting
mode.
In this case, an invalid configuration file was
downloaded (on purpose) via the web. When
the switch rebooted, it detected that the
configuration file was invalid and overwrote
the start-up config with the default
configuration (an empty configuration). Users
are advised to maintain off-line copies of
switch configurations.
Users can send pure IPv4 pings to the other end
of the tunnel.
