Configure Static Routes for the Management Interface
When an IP address that a protocol uses and a static management route exists for the same prefix, the
protocol route takes precedence over the static management route.
To configure a static route for the management port, use the following command.
• Assign a static route to point to the management interface or forwarding router.
CONFIGURATION mode
management route ip-address mask {forwarding-router-address |
ManagementEthernet slot/port}
Example of the show ip route static Command
To view the configured static routes for the management port, use the show ip management-route
command in EXEC privilege mode.
Dell#show ip management-route

Using the Configured Source IP Address in ICMP
Messages
This feature is supported on the platform.
ICMP error or unreachable messages are now sent with the configured IP address of the source interface
instead of the front-end port IP address as the source IP address. Enable the generation of ICMP
unreachable messages through the ip unreachable command in Interface mode. When a ping or
traceroute packet from an endpoint or a device arrives at the null 0 interface configured with a static
route, it is discarded. In such cases, you can configure Internet Control Message Protocol (ICMP)
unreachable messages to be sent to the transmitting device.
Configuring the ICMP Source Interface
You can enable the ICMP error and unreachable messages to contain the configured IP address of the
source device instead of the previous hop's IP address. This configuration helps identify the devices along
the path because the DNS server maps the loopback IP address to the host name, and does not translate
the IP address of every interface of the switch to the host name.
Configure the source to send the configured source interface IP address instead of using its front-end IP
address in the ICMP unreachable messages and in the traceroute command output. Use the ip icmp
source-interface
interface or the ipv6 icmp source-interface interface commands in
Configuration mode to enable the ICMP error messages to be sent with the source interface IP address.
This functionality is supported on loopback, VLAN, port channel, and physical interfaces for IPv4 and IPv6
messages. feature is not supported on tunnel interfaces. ICMP error relay, PATH MTU transmission, and
IPv4 Routing
