• 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.
Trac (switch initiated management trac or responses to switch-destined trac with management port IP address as the source
IP address) for user-specied management protocols must exit out of the management port. In this chapter, all the references to
trac indicate switch-initiated trac and responses to switch-destined trac with management port IP address as the source IP
address.
In customer deployment topologies, it might be required that the trac for certain management applications needs to exit out of the
management port only. You can use EIS to control and the trac 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 specied as a management application,
SSH links to and from an unknown destination uses the management default route.
Protocol Separation
When you congure the application application-type command to congure 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.
