Check works from Console but not in Nagios

Nagios Core 4.3.4
Cisco 3750
from console
root@tgcs017:/usr/local/nagios/etc/objects# /usr/local/nagios/libexec/nm_check_admin_up_oper_down -H 10.2.8.4 -P 2c -C public -c

From Nagios setup
No SNMP response received before timeout

My command
# check_admin_up_oper_down using SNMPv2
define command{
command_name check_switch
command_line $USER1$/nm_check_admin_up_oper_down -H $HOSTADDRESS$ -P 2c -C $ARG1$ $ARG2$
}

My service

# cisco.proto:

define service{
host_name hostname
use generic-service
service_description Interfaces Down
check_command check_switch!cisco3750!-c
check_interval 5
retry_interval 1
}

snmpwalk also works from the Nagios server too

How to set a -T value on the command?

any ideas?

Thank you
Tom
