transport email mail-server

To configure up to five SMTP servers as the domain name server (DNS) names, IPv4 addresses, or IPv6 addresses for Call home, use the transport email mail-server command.

transport email mail-server ip-address [port port-number] [priority priority-number] [use-vrf vrf-name]
Syntax Description

ip-address

Domain name server (DNS) name, IPv4 address, or IPv6 address.

port port-number

(Optional) Specifies the port number. The range is from 1 to 65535. The default port number is 25.

priority priority-number

(Optional) Specifies the priority of the SMTP server. The range is from 1 to 100, with 1 being the highest priority and 100 the lowest. If you do not specify a priority, the default value of 50 is used.

use-vrf vrf-name

(Optional) Specifies the virtual routing and forwarding (VRF) name.

Defaults

None

Command Modes

Call home configuration

Supported User Roles

network-admin

Command History

Release

Modification

5.0(1)

This command was introduced.

Usage Guidelines

You can configure up to five SMTP servers for Call home. The VRF specified in the transport email mail-server command is not used to send messages using HTTP. When CFS distribution is enabled, devices that run Release 4.2 or earlier releases accept only the transport email smtp-server command configurations while devices that run Release 5.0(1) or later releases accept both the transport email smtp-server and transport email mail-server command configurations.

When a device accepts both the transport email smtp-server and transport email mail-server commands, the transport email smtp-server command has a priority of 0, which is the highest. The server specified by this command is tried first followed by the servers specified by the transport email mail-server commands in order of priority.

This command does not require a license.

Examples

This example shows how to configure multiple SMTP servers for Call home messages:
switch(config)# callhome
switch(config-callhome)# transport email mail-server 192.0.2.1 port 33 priority 1 use-vrf 
Red
switch(config-callhome)# transport email mail-server 192.0.2.10 priority 4
switch(config-callhome)# transport email mail-server 172.21.34.193
switch(config-callhome)# transport email smtp-server 10.1.1.174
switch(config-callhome)# transport email mail-server 64.72.101.213 priority 60
switch(config-callhome)# transport email from person@company.com
switch(config-callhome)# transport email reply-to person@company.com
switch(config-callhome)#
Based on the configuration above, the SMTP servers would be tried in this order:

10.1.1.174 (priority 0)

192.0.2.1 (priority 1)

172.21.34.193 (priority 50, which is the default)
64.72.101.213 (priority 60)
