Routing Interfaces and Management Features
Routing interfaces are primarily used to route IPv4 packets. But they are
also used to assign the switch an IP address, which is a requirement for
the management features in Table 27 on page 300. The switch uses the
IP addresses of the routing interfaces as its source addresses when it
communicates with other network devices on the network, such as TFTP
and syslog servers.
If you want to use any of the management functions in Table 27 on
page 300, but not the IPv4 routing feature, assign the switch only one
routing interface. The switch does not route IPv4 packets if it has only one
routing interface. You should assign the routing interface to the VLAN from
which the switch is to access the management network devices. These
devices may be members of the VLAN or accessed through routers or
Layer 3 devices.
The switch is capable of accessing network devices from any VLAN that
has a routing interface. So if you use the IPv4 routing feature and add
routing interfaces to multiple VLANS, the switch will be able to use the
different routing interfaces to access management devices on different
VLANs.
