Channel Groups
Use this tab to provision the channel group. The following table describes the Channel Groups tab page fields and buttons.
Note
This option is available only when the card is in L2 over DWDM mode.
Item
Description
Channel Group
Displays the name of the channel group. The channel group is a logical port bundling two or more physical ports
Name
Displays the user-defined name of the channel group.
Ports
Displays the list of the bundled ports (that is, the ports that belong to the same channel group).
There are three type of ports:
 •
1-1 (TEN-GE)
 •
2-1 (TEN-GE)
 •
4-1 (TEN-GE)
LACP Mode
Displays the Link Aggregation Control Protocol (LACP) mode. Choose a LACP mode from the drop-down list and click Apply to change the mode.
 •
On
 •
Active
 •
Passive
Hashing
Choose a Hashing type from the drop-down list. The available options are:
 •
Ucast SA VLAN incoming port
 •
Ucast DA VLAN incoming port
 •
Ucast SA DA VLAN incoming port
 •
Ucast SRC IP TCP UDP
 •
Ucast DST IP TCP UDP
 •
Ucast SRC DST IP TCP UDP
Admin State
Choose an administrative state from the drop-down list and click Apply to change the port service state unless network conditions prevent the change. Admin states include:
 •
IS—Moves the port to in service. The port service state changes to IS-NR.
 •
OOS, DSBLD—Removes the port from service and disables it. The port service state changes to OOS-MA,DSBLD.
Service State
Displays the autonomously generated state that gives the overall condition of the port. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. For additional state information, see States.
MTU
Sets the maximum transfer unit, which is the largest acceptable packet size configured for that port. The valid range is from 64 to 9700. The default size is 9700.
To set this option, choose one of the card modes:
 •
L2 over DWDM
 •
10GE TXP
 •
10GE MXP
 •
20GE MXP
Mode
Displays the mode in which the card is present.
In Ethernet mode, the values are:
 •
Auto (default, GE ports only)
 •
1000 Mbps (GE ports only)
 •
10000 Mbps (default, 10GE ports only)
Expected Speed
Displays the expected port speed. Expected speed can only be 10000Mbps for the 10GE port and 100Mbps or 1000Mbps for the 1GE ports.
Duplex
Displays the duplex setting of the port. The valid values are Auto, Full, and Half.
Committed Info Rate
Sets the guaranteed information rate as provided by the service provider service-level agreement.
Committed Burst Size
Sets the maximum number of bits transferred per second.
Excess Burst Size
Sets the maximum number of bits credited for later transfer in the event the committed burst rate cannot be transmitted.
NIM
Sets the port network interface mode (NIM). This parameter classifies port types designed for the Metro Ethernet market to simplify deployment, management, and troubleshooting.
The options are:
 •
UNI Mode—Provisions the port as a user-to-network interface (UNI). This is the interface that faces the subscriber.
When a port is in UNI Mode, tagging can be configured as transparent or selective. In transparent mode, only SVLANs in the node VLAN database can be configured. In selective mode, CVLAN to SVLAN relationships can be defined.
 •
NNI Mode—Provisions the port as a network-to-network interface (NNI). This is the interface that faces the service provider network.
To set this option, the card mode must be L2 over DWDM.
Ingress CoS
Provisions the IEEE 802.1p ingress Class of Service (CoS). The CoS bits set the Ethernet frame priority.
The options are:
 •
0—(default) Sets the CoS bits to 0.
 •
1—Sets the CoS bits to 1.
 •
2—Sets the CoS bits to 2.
 •
3—Sets the CoS bits to 3.
 •
4—Sets the CoS bits to 4.
 •
5—Sets the CoS bits to 5.
 •
6—Sets the CoS bits to 6.
 •
7—Sets the CoS bits to 7.
 •
Trust—Copies the CoS bits from the incoming packet.
 •
CVLAN—CoS can be provisioned based on CVLAN.
 •
DSCP—Uses the DiffServ Code Point (DSCP) value from the header of the transported IP packet.
Inner Ethertype (Hex)
Defines the inner Ethertype field. The Ethertype field indicates which protocol is transported in an Ethernet frame.
The Inner Ethertype applies only to ports provisioned in UNI mode. It does not apply to ports provisioned as NNI mode. The ports must be OOS before the Inner Ethertype can be provisioned. The default is 8100 (IEEE Std 802.1Q customer VLAN tag type) and the range is 0x0600 to 0xFFFF.
To set this option, the card mode must be L2 over DWDM.
Outer Ethertype (Hex)
Defines the outer Ethertype field. The Ethertype field indicates which protocol is transported in an Ethernet frame. The default is 8100 (IEEE Std 802.1Q customer VLAN tag type) and the range is 0x0600 to 0xFFFF.
To set this option, the card mode must be L2 over DWDM.
MAC Learning
If checked, enables enables or disables MAC learning for the port. MAC learning is used by Layer 2 switches to learn the MAC addresses of network nodes to know where to send traffic. Layer 2 switches, including the GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards in L2 over DWDM mode, maintain a MAC learning table that associates the MAC addresses and VLANs with a given port.
Note
MAC address table aging is 300 seconds. It cannot be changed.
To set this option, the card mode must be L2 over DWDM.
Create
Creates new channel groups.
Add/Remove Ports
Add or Removes port from the channel group.
Delete
Deletes the selected channel group.
Apply
Applies changes made to the channel groups.
Reset
Cancels any changes to the channel groups and returns it to its last-saved settings.
Help
Displays context-sensitive help.
