Configuration Tasks
To configure duplex operation on an interface, use the duplex command in interface configuration mode.
Use the no form of this command to return to the default value.
Configuring the Media Type
The 2-Port Gigabit Ethernet SPA supports RJ-45 and fiber ports. Use the media-type configuration
command to select either the RJ-45 or fiber media for a given port.
Enabling Autonegotiation
To re-enable autonegotiation on a Fast Ethernet or Gigabit Ethernet interface, use the following
command in interface configuration mode:
Configuring a Subinterface on a VLAN
Note You can configure no more than 8100 802.1Q VLAN subinterfaces per Ethernet SPA in software releases
prior to Cisco IOS XE Release 2.5. Beginning in Cisco IOS XE Release 2.5, you can use the hw-module
subslot ethernet vlan unlimited command to increase the system default and enable support for
configuration of up to 4094 dot1q VLANs per port per SPA. The default is 8100 VLANs.
You can configure subinterfaces on the Fast Ethernet SPA interfaces and Gigabit Ethernet SPA interfaces
on a VLAN using IEEE 802.1Q encapsulation. Cisco Discovery Protocol (CDP) is disabled by default
on the 2-Port Gigabit Ethernet SPA interfaces and subinterfaces on the Cisco ASR1000-SIP10.
Command Purpose
Router(config-if)# speed {10 | 100 | 1000} Configures the interface to transmit at 10 Mbps, 100
Mbps, or 1000 Mbps. (The 1000 keyword is only valid
for Gigabit Ethernet.)
Command Purpose
Router(config-if)# duplex {full | half} Specifies full- or half-duplex operation.
Command Purpose
Router(config-if)# media-type {10baset |
100baset | rj45 | gbic}
Specifies the physical connection on an interface.
Command Purpose
Router(config-if)# negotiation auto Enables autonegotiation on a Fast Ethernet SPA
interface on a Cisco ASR1000-SIP10 or a Gigabit
Ethernet SPA interface on the Cisco ASR1000-SIP10.
Advertisement of flow control occurs.
