The management-access command lets you define an internal management interface using the IP address of the firewall interface specified in mgmt_if. (The interface names are defined by the nameif command and displayed in quotes, " ", in the output of the show interface command.)
The management-access command is supported for the following through an IPSec VPN tunnel only, and you can define only one management interface globally:
SNMP polls to the mgmt_if
HTTPS requests to the mgmt_if
ASDM access to the mgmt_if
Telnet access to the mgmt_if
SSH access to the mgmt_if
Ping to the mgmt_if
Syslog polls to the mgmt_if
NTP requests the mgmt_if
