Modifying the MAC Address on the Interface
The Gigabit Ethernet SPAs use a default MAC address for each port that is derived from the base address that is stored in the electrically erasable programmable read-only memory (EEPROM) on the backplane of the Cisco 10000 series router.
To modify the default MAC address of an interface to some user-defined address, use the following command in interface configuration mode:
To return to the default MAC address on the interface, use the no form of the command.
Verifying the MAC Address
To verify the MAC address of an interface, use the show interfaces gigabitethernet privileged EXEC command and observe the value shown in the address field.
The following example shows output from the show interfaces tengigabitethernet command on a 1-Port 10-Gigabit Ethernet SPA in slot 7, SPA subslot 0. The second line of the output identifies the type of SPA and its MAC address.

MAC address accounting provides accounting information for IP traffic based on the source and destination MAC addresses of the LAN interfaces. MAC address accounting calculates the total packet and byte counts for a LAN interface that receives or sends IP packets to or from a unique MAC address. It also records a timestamp for the last packet received or sent. With MAC address accounting, you can determine how much traffic is being sent to and/or received from various peers at NAPS/peering points.
To enable MAC address accounting on an interface, use the following command in interface configuration mode:
Configuring Autonegotiation on an Interface
Autonegotiation is enabled by default and can be disabled on the Gigabit Ethernet SPAs. During autonegotiation, advertisement for flow control, speed, and duplex occurs. If autonegotiation is disabled on one end of a link, it must be disabled on the other end of the link. If one end of a link has autonegotiation disabled while the other end of the link does not, the link does not come up properly on both ends. Flow control is always negotiated when autonegotiation is enabled.
Disabling Autonegotiation
To disable autonegotiation on Gigabit Ethernet SPAs, use the following command in interface configuration mode:
Router(config-if)# no negotiation auto
Disables autonegotiation on a Gigabit Ethernet SPA interface on the Cisco 10000 SIP-600. No advertisement of flow control occurs.
Enabling Autonegotiation
To re-enable autonegotiation on a Gigabit Ethernet interface, use the following command in interface configuration mode:
Router(config-if)# negotiation auto
Enables autonegotiation on a Gigabit Ethernet SPA interfaceson the Cisco 10000 SIP-600. Advertisement of flow control occurs.
Modifying the Interface MTU Size
The Cisco IOS software supports three different types of configurable maximum transmission unit (MTU) options at different levels of the protocol stack:

Note
Interface MTU Configuration Guidelines
When configuring the interface MTU size on a Gigabit Ethernet SPA on a Cisco 10000 series router, consider the following guidelines:
•

Note
•
•
Interface MTU Configuration Task
To modify the MTU size on an interface, use the following command in interface configuration mode:
To return to the default MTU size, use the no form of the command.
Verifying MTU Size
To verify the MTU size for an interface, use the show interfaces command in privileged EXEC command and observe the value shown in the MTU field.
The following example shows an MTU size of 1500 bytes for interface port 1 (the second port) on the Gigabit Ethernet SPA installed in the top subslot (0) of the SIP that is located in slot 2 of the Cisco 10000 series router:
Router# show interfaces gigabitethernet 2/0/1GigabitEthernet2/0/1 is up, line protocol is upHardware is GigEther SPA, address is 000a.f330.2e40 (bia 000a.f330.2e40)Internet address is 2.2.2.1/24MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,reliability 255/255, txload 1/255, rxload 1/255Encapsulation ARPA, loopback not setKeepalive not supportedConfiguring the Encapsulation Type
By default, the interfaces on the Gigabit Ethernet SPAs support Advanced Research Projects Agency (ARPA) encapsulation. They do not support configuration of service access point or SNAP encapsulation for transmission of frames; however, the interfaces will properly receive frames that use service access point and SNAP encapsulation.
The other encapsulation supported by the SPA interfaces is IEEE 802.1Q encapsulation for virtual LANs (VLANs). To create a subinterface on a SPA interface port and configure the subinterface on a VLAN using IEEE 802.1Q encapsulation, use the following command in subinterface configuration mode.:
Configuring the Hold Queue
You can limit the size of the input queue on a Gigabit Ethernet SPA in units of packets. The input hold queue prevents a single interface from flooding the network server with too many input packets. Further input packets are discarded if the interface has too many input packets outstanding in the system. The default input hold queue limit is 75 packets.
To modify the input hold queue on a Gigabit Ethernet SPA, use the following command in interface configuration mode:
Configuring Ethernet VLANs
The Cisco 10000 router supports virtual local area networks (VLANs) to separate a service provider's subscriber traffic. Each Gigabit Ethernet SPA supports up to up to 8000 VLANs.
To configure Ethernet VLANs on an interface, refer to the Cisco 10000 Series Router Broadband Aggregation, Leased-Line, and MPLS Configuration Guide at:
http://cisco.com/en/US/products/hw/routers/ps133/products_installation_and_configuration_guides_list.html
Configuring EtherChannels
An EtherChannel bundles individual Gigabit Ethernet links into a single logical link that provides the aggregate bandwidth of up to eight physical links. This feature helps improve the cost effectiveness of a device by increasing cumulative bandwidth without requiring hardware upgrades. In addition, IEEE 802.3ad link bundling provides a capability to dynamically provision, manage, and monitor various aggregated links and enables interoperability between various Cisco devices and devices of third-party vendors.
Note
Gigabit EtherChannels on Multiport SPAs
When using multiport Gigabit Ethernet SPAs for PPPoE sessions, the active and backup member-links must have the same port number on each line card. For example, there is a 1+1 redundant Gigabit EtherChannel on a 2-Port Gigabit Ethernet SPA. The member links are 1/0/0 and 1/1/0, and 2/0/0 and 2/1/0. You can create the redundant Gigabit EtherChannels on the following ports:
•
•
You cannot create the redundant Gigabit EtherChannels on these ports:

Note
For information on configuring EtherChannels on a Cisco 10000 series router, refer to the IEEE 802.3ad Link Bundling publication at this URL:
http://cisco.com/en/US/products/ps6566/products_feature_guide09186a00807627ce.html
Configuring a Priority Queue on Gigabit Ethernet SPAs
The Gigabit Ethernet SPAs provide the ability to separate high-priority traffic from low-priority traffic and places the traffic in the appropriate interface queue. Priority and nonpriority traffic are separated at the SIP to prevent the dropping of high-priority traffic in an oversubscription case.
Note
The following classification types are available to prioritize ingress traffic on the Gigabit Ethernet SPAs:
•
•
•
•
•
Classifying Ingress VLAN Traffic
To classify ingress VLAN traffic based on the 802.1Q priority bits, use the following commands in interface and subinterface configuration mode:
Classifying Ingress IP Traffic According to DSCP Bits
To classify ingress IP traffic based on the value of the DSCP bits, use the following commands in the interface configuration mode:
Classifying Ingress IP Traffic According to IP Precedence Bits
To classify ingress IP traffic based on the value of the IP precedence bits, use the following commands in interface configuration mode:
Classifying Ingress IPv6 Traffic According to Traffic-Class Bits
To classify ingress IPv6 traffic based on the value of the traffic-class bits, use the following command in interface configuration mode:
Classifying Ingress MPLS Traffic According to EXP Bits
To classify ingress MPLS traffic based on the value of the EXP bits, use the following commands in interface configuration mode:
Preprovisioning SIPs and SPAs
Preprovisioning is an optional configuration task for the Cisco 10000 SIP-600 and SPAs. It allows you to preprovision a line card slot in the Cisco 10000 series router to accept a particular SIP, and to preconfigure the SPA interfaces without the SIP being physically present in the chassis. This feature allows planning for future configurations.
For preprovisioning a SPA, the subslot must be physically empty or gracefully deactivated. For information on gracefully deactivating a SPA, refer to the "Online Insertion and Removal of a SIP" section on page 13-3.
Tip
To preprovision SIPs and SPAs, perform the following steps:
Step 1
Router(config-if)# card slot 4jacket-1
Specifies the preprovisioning of a SIP in a particular line card slot.
•
•
Step 2
Router(config-if)# card slot subslot spa-type
Specifies the preprovisioning of a SPA interface.
•
•
•
The following example preprovisions line card slot 3 to accept a Cisco 10000 SIP-600 and a 2-Port Gigabit Ethernet SPA in subslot 0:
Router(config)# card 3 4jacket-1Router(config)# card 3/0 spa-2x1ge-v2Removing Preprovisioning on a SIP and SPA
To remove a preprovisioning configuration from a line card slot, use the no card slot subslot spa-type command. This removes all configuration information for that slot, as well as any information in the SNMP MIB database about the card and its card slot.
To remove preprovisioning configuration information, the SIP slot or SPA subslot must be physically empty or gracefully deactivated. For information on deactivating SIPs and SPAs, refer to the "Online Insertion and Removal of a SIP" section on page 13-3.
Configuring the Media Type on the 2-Port Gigabit Ethernet SPA
Use the media-type configuration command to modify the default physical connection type from small-form-factor pluggable (SFP) optical transceiver to RJ45 (copper port). This command is only applicable to the 2-Port GE SPA.
To modify the media type configuration, perform the following steps:
The following example configures the media type on a 2-Port Gigabit Ethernet SPA:
router(config)# interface g2/0/0router(config-if)# media-type sfpVerifying the Interface Configuration
Besides using the show running-configuration command to display your router configuration settings, you can use the show interfaces gigabitethernet command to get detailed information on a per-port basis for your Gigabit Ethernet SPAs.
Verifying Per-Port Interface Status
To find detailed interface information on a per-port basis for the Gigabit Ethernet SPAs, use the show interfaces gigabitethernet command. For a description of the command output, see Chapter 12, "SIP and SPA Commands."
The following example provides sample output on a 1-Port 10-Gigabit Ethernet SPA in slot 7, SPA subslot 0, port 0:
Router# show interfaces tengigabitethernet 7/0/0TenGigabitEthernet7/3/0 is up, line protocol is upHardware is TenGigEther SPA, address is 0001.6380.d2cc (bia 0001.6380.d2cc)MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec,reliability 255/255, txload 1/255, rxload 1/255Encapsulation ARPA, loopback not setKeepalive set (10 sec)Full Duplex, 10000Mbps, link type is force-up, media type is 10GBase-LRoutput flow-control is unsupported, input flow-control is XONARP type: ARPA, ARP Timeout 04:00:00Last input never, output 00:00:01, output hang neverLast clearing of "show interface" counters neverInput queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0Interface TenGigabitEthernet7/3/0 queueing strategy: PXF Class-based5 minute input rate 0 bits/sec, 0 packets/sec5 minute output rate 0 bits/sec, 0 packets/sec0 packets input, 0 bytes, 0 no bufferReceived 0 broadcasts (0 IP multicasts)0 runts, 0 giants, 0 throttles0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored0 watchdog, 0 multicast, 0 pause input2241 packets output, 134460 bytes, 0 underruns0 output errors, 0 collisions, 0 interface resets0 babbles, 0 late collision, 0 deferred0 lost carrier, 0 no carrier, 0 PAUSE output0 output buffer failures, 0 output buffers swapped outRouter#Configuration Examples
