Netmiko device_type for ProCurve J4900B Switch 2626 (telnet) #3031

Open ferberat opened 1 year ago

ferberat commented 1 year ago

I have a Problem with ProCurve J4900B Switches. I am not able to successfully connect to Device. I tried some device_types: hp_procurve_telnet,aruba_procurve_telnet,cisco_ios_telnet.......... But none of them work.

Netmiko Logs:

hp_procurve_telnet is probably the right type. It looks like the telnet_login() function/method is probably not handling your case for some reason.

What happens if you try:

_net_connect = ConnectHandler(device_type="hp_procurve_telnet", ip=ipaddr, username=var_username, password=var_password, fast_cli=False, global_delay_factor=4)

@ferberat If you add the "session_log" to ConnectHandler, what does that show you?
