Chapter 10 Configuring Interface Characteristics
Configuring Ethernet Interfaces
• TFTP
• Secure Shell (SSH)
• DHCP-based autoconfiguration
• SMNP (only the ENTITY-MIB and the IF-MIB)
• IP ping
• Interface features
–
Speed—100 Mb/s (nonconfigurable)
–
Duplex mode—Full (nonconfigurable)
–
Loopback detection
• IPv4 and IPv6 access control lists (ACLs)
Caution Before enabling a feature on the Ethernet management port, make sure that the feature is supported. If
you try to configure an unsupported feature, such as Cisco Discovery Protocol (CDP), DHCP relay
agent, or routing protocols, on the Ethernet Management port, the feature might not work properly, and
the switch might fail.
Layer 3 Routing Configuration Guidelines
When Layer 3 routing is enabled, you should be aware of these guidelines:
• If Routing Information Protocol (RIP) or Open Shortest Path First (OSPF) is enabled, RIP or OSPF
advertises routes with the internal Ethernet management port. By default, RIP and OSPF are
disabled.
• Virtual private network routing and forwarding (VRF) can be used to separate the routing domains
for the Ethernet management port and for data packets.
• The default gateway is not available. It is available when IP routing is disabled. You can configure
a default route to replace the default gateway.
Monitoring the Ethernet Management Port
To display the link status, use the show interfaces fastethernet 0 privileged EXEC command.
