Monitoring VLAN and S-VLAN Subinterfaces

This chapter describes how to monitor VLAN and S-VLAN subinterfaces on E Series routers. You can use the show commands described in this chapter to display information about your Ethernet configuration and to monitor Ethernet interfaces.

Note: The E120 and E320 routers output for monitor and show commands is identical to output from other E Series routers, except that the E120 and E320 routers output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).

This chapter contains the following sections:

• Monitoring VLAN Subinterfaces
• Monitoring Interface Rate Statistics for VLAN Subinterfaces
• Monitoring Fast Ethernet VLAN or S-VLAN Subinterfaces
• Monitoring Gigabit Ethernet or 10-Gigabit Ethernet VLAN or S-VLAN Subinterfaces
