traffic for such end-user-originated sessions destined to management port ip1 is handled using the EIS route lookup. Handling of Transit Traffic (Traffic Separation) This is forwarded traffic where destination IP is not an IP address configured in the switch. • Packets received on the management port with destination on the front-end port is dropped. • Packets received on the front-end port with destination on the management port is dropped. • A separate drop counter is incremented for this case. This counter is viewed using the netstat command, like all other IP layer counters. Consider a scenario in which ip1 is an address assigned to the management port and ip2 is an address assigned to any of the front panel port of a switch. End users on the management and front panel port networks are connected. In such an environment, traffic received in the management port destined on the data port network is dropped and traffic received in the front-end port destined on the management network is dropped. Mapping of Management Applications and Traffic Type The following table summarizes the behavior of applications for various types of traffic when the management egress interface selection feature is enabled. Table 30. Mapping of Management Applications and Traffic Type Traffic type / Application type Switch initiated traffic Switch-destined traffic Transit Traffic EIS Management Application Management is the preferred egress port selected based on route lookup in EIS table. If the management port is down or the route lookup fails, packets are dropped. If source TCP/UDP port matches a Traffic from management application and source management port IP address is management port IP to data port and address, management port is the from data port to preferred egress port selected based management port on route lookup in EIS table. If is blocked management port is down or route lookup fails, packets are dropped Non-EIS management application Front-end default route If source TCP/UDP port matches a will take higher management application and the precedence over source IP address is a management management default route port IP address, the management and SSH session to an port is the preferred egress port unknown destination uses selected based on route lookup in the front-end default route EIS table. If the management port is only. No change in the down or the route lookup fails, existing behavior. packets are dropped Traffic from management port to data port and from data port to management port is blocked • EIS is enabled implies that EIS feature is enabled and the application might or might not be configured as a management application • EIS is disabled implies that either EIS feature itself is disabled or that the application is not configured as a management application Transit Traffic Internet Group Management Protocol (IGMP) 403
