MC-B106 Adding SL16, SLQ41, or SLT1 Boards Failed on the NMS

If the OptiX OSN 1500 used the R1CXL or R2CXL board, adding SL16, SLQ41, or SLT1 service boards failed on the NMS. The fault was rectified by adding appropriate service boards or higher-capacity cross-connect boards.

Product

OptiX OSN 1500

Fault Type

Others

Symptom

If the OptiX OSN 1500 used the R1CXL or R2CXL board, adding SL16, SLQ41, or SLT1 service boards failed on the NMS.

Cause Analysis

When the R1CXL or R2CXL was used on the OptiX OSN 1500, slots 11, 12, and 13 provided a maximum bandwidth of 622 Mbit/s, 1.25 Gbit/s, and 1.25 Gbit/s, respectively. None of these slots could provide the maximum transmission bandwidth (shown below) required by the SL16, SLQ41, or SLT1boards.

SL16 (one channel of STM-16): 1 x STM-16 = 1 x 2.5 Gbit/s = 2.5 Gbit/s

SLT1 (12 channels of STM-1): 12 x STM-1 = 12 x 155 Mbit/s = 1.86 Gbit/s

SLQ41 (four channels of STM-1/STM-4): 4 x STM-4 = 4 x 622 Mbit/s = 2.5 Gbit/s

Procedure

Used appropriate service boards or higher-capacity cross-connect boards. 

NOTE:

For details about how to choose appropriate service boards, see the "Valid Slots" sections in the hardware description manual.

The backup route configuration between the three layer and two layer Switch

The backup route configuration OSN 8800 between the three layer and two layer Switch, common is Cisco VRRP, GLBP, HSRP. Also can do the link aggregation.

Switchport mode trunk

If you want to know is port aggregation!! different manufacturers have different commands, such as:

Cisco command line configuration:

CLI command line: SW#conf t

SW (config) #interface range f1/1 -2

SW (config-if) #channel-group 1 mode desirable/on

SW (config-if) #swithport

SW (config-if) #switchport mode trunk

SW (config-if) #switchport trunk encap dot1q

Through interface Port-channel 1 into the port channel

Huawei port aggregation configuration:

Huawei switch port polymerization can be achieved through the following command:

S3250 (config) #link-aggregation port_num1 to port_num2 ingress-egress}{ingress |

Where port_num1 is the starting port, port_num2 port number is terminated.Ingress/ingress-egress this parameter option chosen for ingress-egress.

When the port aggregation please pay attention to the following points:

● 1, each Huawei switch only supports 1 aggregation group

● 2, each aggregate group only 4 port polymerization.

● 3, participate in the port number must be continuous polymerization.

The following command control is realized through polymerization ports can be:

S3026 (config) #show link-aggregation [master_port_num]

Where master_port_num is in the polymerization of port port number that portminimum.

Through this command is used to display the aggregation group including what port and other related parameters and aggregate port.

Ruijie configure port polymerization:

Switch#configure terminal

Switch (config) #interface range FastEthernet 1/1-2

Switch (config-if-range) #port-group 5

Switch (config-if-range) #switchport mode trunk

You can use the command #interface aggregateport n in global configuration mode (n to AP) to create a AP (if AP n does not exist).

Flow equilibrium configuration of aggregate port

Aggregateport load-balance {dst-mac| src-mac |ip}

Flow balance, set the AP, choose to use the algorithm:

Dst-mac: process flow distribution according to the input message’s destination MAC address. In AP each link, the destination MAC address the same message was sent to the same interface, message distribution to MACdifferent to different interface

Src-mac: process flow distribution according to the source MAC address inputmessage. In AP each link, message distribution from different address to a different interface, the message from the same address using the same interface.

Ip: traffic distribution based on the source IP and destination IP.
