Management Source IP Address

In many cases network operators prefer to have a single IP address for the switch that is used for management operations like switch configuration, receiving remote log files, ping, and so forth. That IP address is needed for building firewall rules so that network switches can be easily identified. It is also required for identifying management traffic and exact management target in network logs.

The following protocols are supported by the feature:

  • FTP

  • TFTP

  • NTP

  • Syslog

  • TACACS

  • SSH, SSHD, SCP

  • Ping

  • Traceroute

  • SNMP
