Management interface

The Management interface provides management access to the network device. You can congure the Management interface, but the

conguration options on this interface are limited. You cannot congure gateway addresses and IP addresses if it appears in the main

routing table, and proxy ARP is not supported on this interface.

1 Enter 1/1/1 to congure the Management interface in CONFIGURATION mode (1 to 6).

interface mgmt 1/1/1

2 Congure an IP address and mask on the Management interface in INTERFACE mode.

ip address A.B.C.D/prefix-length

3 (Optional) Congure DHCP client operations in INTERFACE mode.

dhcp

4 Enable the Management interface in INTERFACE mode.

no shutdown

5 Save the conguration.

do commit

Congure management interface

OS10(config)# interface mgmt 1/1/1

OS10(conf-if-ma-1/1/1)# ip address 10.1.1.10/24

OS10(conf-if-ma-1/1/1)# dhcp

OS10(conf-if-ma-1/1/1)# no shutdown

OS10(conf-if-ma-1/1/1)# do commit

VLAN interfaces

VLANs are logical interfaces and are, by default, in L2 mode. Physical interfaces and port-channels can be members of VLANs. You cannot

simultaneously use egress rate shaping and ingress rate policing on the same VLAN.

OS10 supports inter-VLAN routing — L3 routing in VLANs. You can add IP addresses to VLANs and use them in routing protocols in the

same manner that physical interfaces are used. You cannot assign an IP addresses to VLAN1 (default).

When using VLANs in a routing protocol, you must congure the no shutdown command to enable the VLAN for routing trac. In

VLANs, the shutdown command prevents L3 trac from passing through the interface — L2 trac is unaected by this command.

1 Congure an IP address in A.B.C.D/x format on the interface in INTERFACE mode. The secondary IP address is the interface’s backup

IP address — you can congure up to eight secondary IP addresses.

ip address ip-address/mask [secondary]

2 Save the conguration.

do commit

Congure VLAN

OS10(config)# interface vlan 10

OS10(conf-if-vl-10)# ip address 1.1.1.2/24

OS10(conf-if-vl-10)# do commit

Loopback interfaces

A loopback interface is a virtual interface in which the software emulates an interface. Because a loopback interface is not associated to

physical hardware entities, the loopback interface status is not aected by hardware status changes.

Packets routed to a loopback interface are processed locally to the OS10 device. Because this interface is not a physical interface, you can

congure routing protocols on this interface to provide protocol stability. You can place loopback interfaces in default L3 mode.
