Cisco ASA syslog default UDP port 514 change

shalendra2 — Tue, 12 Mar 2019 06:57:10 GMT

Hi Team,

We want to change the syslog forwarding port 514 to 516 in Cisco ASA firewall. Can we change that? If it is then, How?

Because if we are changing it. It gives error "The port Number for UDP must be either 514 or between 1025 to 65535".

Please help us.

Regards,

Shalendra

Hello Shalendra,

By default the ASA uses UDP 514 port for sending the sysylog information . So port no 516 cannot be configured. The port range has to be in the range of 1025-65535

ciscoasa(config)# logging host tftp 1.1.1.1 udp/516
WARNING: interface Ethernet0/1 security level is 0.
ERROR: Port '516' is not within the range 1025-65535.
