Configuring Interfaces

This chapter contains overview information on interfaces supported by SFTOS, along with information on

configuring physical interfaces, in the following sections:

• Interface Support in SFTOS

• Viewing Interface Information on page 112

• Viewing Layer 3 Interface Information on page 117

• Configuring Physical Interfaces on page 117

• Bulk Configuration on page 126

Interface Support in SFTOS

SFTOS supports the following interface types (SFTOS does not support null interfaces.):

• 10/100/1000 Ethernet ports

• Gigabit Ethernet ports (1G)

• 10 Gigabit Ethernet ports (10G)

• Loopback (logical interface): For

loopback interface syntax, see the System Configuration chapter in

the SFTOS Command Reference. For information on the loopback ACL, see Protecting the

Management Interface with a Loopback ACL on page 201.

• Layer 2 and Layer 3 VLANs: See VLANs on page 207 and VLAN Routing on page 262.

• Layer 2 and Layer 3 port channels (LAGs): See Link Aggregation on page 165.

• Console port (TTY emulation): See Connecting to the Console Port on page 29.

• IP-based Management Ethernet: See Creating the Management IP Address on page 67.

In the S-Series, you can place physical interfaces, port channel interfaces, and VLANs in either Layer 2 or

Layer 3 mode (Table 7-3).
