The management EIS feature is applicable only for the out-of-band (OOB) management port. References

in this section to the management default route or static route denote the routes configured using the

management route command. The management default route can be either configured statically or

returned dynamically by the DHCP client. A static route points to the management interface or a

forwarding router.

Transit traffic (destination IP not configured in the switch) that is received on the front-end port with

destination on the management port is dropped and received in the management port with destination

on the front-end port is dropped.

Switch-destined traffic (destination IP configured in the switch) is:

Received in the front-end port with destination IP equal to management port IP address or

management port subnet broadcast address is dropped.

Received in the management port with destination IP not equal to management IP address or

management subnet broadcast address is dropped.

Traffic (switch initiated management traffic or responses to switch-destined traffic with management port

IP address as the source IP address) for user-specified management protocols must exit out of the

management port. In this chapter, all the references to traffic indicate switch-initiated traffic and

responses to switch-destined traffic with management port IP address as the source IP address.

In customer deployment topologies, it might be required that the traffic for certain management

applications needs to exit out of the management port only. You can use EIS to control and the traffic

can exit out of any port based on the route lookup in the IP stack.

One typical example is an SSH session to an unknown destination or an SSH connection that is destined

to the management port IP address. The management default route can coexist with front-end default

routes. If SSH is specified as a management application, SSH links to and from an unknown destination

uses the management default route.

Protocol Separation

When you configure the application application-type command to configure a set of

management applications with TCP/UDP port numbers to the OS, the following table describes the

association between applications and their port numbers.
