Enabling Autonegotiation
To re-enable autonegotiation on a Fast Ethernet or Gigabit Ethernet interface, use the following command in
interface configuration mode:
Purpose
Command
Enables autonegotiation on a Fast Ethernet SPA
interface on a Cisco ASR1000-SIP10 or a Gigabit
Ethernet SPA interface on the Cisco ASR1000-SIP10.

Configuring a Subinterface on a VLAN
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.
Note
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.
To configure a SPA subinterface on a VLAN, use the following commands beginning in global configuration
mode:
