Hi, i found this information useful, as i was searching for a way to get information from hp1920 
which port has learned which mac (for network intrusion).

I was pulling my hair out to get this via snmp, apparently its not possible - so lets do the expect approach.... ;)

maybe somone finds this useful - it did take me a while to find appropriate commands...

# cat ./hp1920_getmacs.exp
#!/usr/bin/expect -f
set timeout 60
set host [lindex $argv 0]
set user [lindex $argv 1]
set pass [lindex $argv 2]

stty echo
eval spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no $user@$host
expect "password:"
send "$pass\r"
expect ""
send "_cmdline-mode on\r"
expect "\[Y\/N\]"
send "Y\r"
expect "password:"
send "Jinhua1920unauthorized\r"
expect ""
send "screen-length disable\r"
expect ""
send "display mac-address\r"
expect ""


# ./hp1920_getmacs.exp  admin admin
