'config system modem' not available in SSH session but is available in TELNET

[timmy8ken]

Hello,

When I connect to our FortiGate 100D via SSH I am not able to edit 'config system modem', and I get the following error returned:

FG100D********* # config system modem
command parse error before 'modem'
Command fail. Return code 1

If I run 'show system ?' the modem option is not listed:

FG100D********* # show system

3g-modem Configure 3G modem.
accprofile Configure system admin access group.
***/SNIP/***
ipv6-neighbor-cache Configure IPv6 neighbor cache table.
ipv6-tunnel Configure IPv6/IPv4 in IPv6 tunnel.
monitors Configure system monitors.
nat64 Configure NAT64.
network-visibility Configure network visibility settings.
ntp Configure system NTP information.
object-tag Configure object tags.
****/SNIP/****

If I then connect to the same firewall using telnet instead of SSH, the commands work as expected:

FG100D********* # config system modem

FG100D********* (modem) #

and the modem field is listed:

FG100D********* # config system
3g-modem Configure 3G modem.
accprofile Configure system admin access group.
****/SNIP/****
ipv6-neighbor-cache Configure IPv6 neighbor cache table.
ipv6-tunnel Configure IPv6/IPv4 in IPv6 tunnel.
modem Configure MODEM.
monitors Configure system monitors.
nat64 Configure NAT64.
network-visibility Configure network visibility settings.
ntp Configure system NTP information.
object-tag Configure object tags.
****/SNIP/****

The commands are also available through the 'CLI Console' in the web GUI, my guess is that it uses a TELNET session in the backend to make that connection.

I have raised a support ticket with FortiNet (1457401), but I thought I would post this here incase someone has seen it before.

Regards,

Tim

It's not all bad, we are only using the modem functionality until our redundant link is in place at the end of the month. After that it will be disabled along with Telnet!!
