Packet Header Analysis

In this user interface, you can collect header data for diagnosing complex network faults.

In the NE Explorer, choose Diagnosis&Maintenance > Packet Header Analysis from the navigation tree.

You are an NMS user with "Administrators" authority.

The packet header analysis function can be used to collect header data for diagnosing complex network faults.

NOTE:

The U2000 only collects packet header data for administrators. It does not analyze or process packet headers or services.
Packet header analysis must be manually enabled by administrators.
Packet headers of Layer 2 Service and Layer 3 Service cannot be collected at the same time.

Packet header analysis applies to the IF and packet boards of the OptiX RTN 950N, OptiX RTN 905E, and OptiX RTN 950A.

**Table 1** Parameters required for configuring packet header analysis
Parameter	Value	Description
Board	Character string Example: 1-EG4	Indicates the board name.
Port	Character string Example: 1-(port-1)	Indicates the port name.
Packet Capture Mode	Once Capture, Continuing Capture Once Capture	Indicates the packet capture mode.
Number of Captured Packets	1 to 1000 Default: 100.	Indicates the number of packet headers.
Packet Header Length(byte)	16 to 74 Default: 16.	Indicates the length of each packet header.
Packet Capture Direction	Ingress, Egress	Indicates the packet direction.

**Table 2** Layer 2 Service
Parameter	Value	Description
Source MAC Address	Format: XX-XX-XX-XX-XX-XX (X is a hexadecimal number) Default: 00-00-00-00-00-00.	Indicates the source MAC address of a packet.
Destination MAC Address	Format: XX-XX-XX-XX-XX-XX (X is a hexadecimal number) Default: 00-00-00-00-00-00.	Indicates the destination MAC address of a packet.
Outer VLAN	Number	Indicates the outer VLAN ID.
Inner VLAN	Number	Indicates the inner VLAN ID.
Ethernet Type (Hexadecimal)	A string of hexadecimal characters The value ranges from 00 00 to FF FF. You can enter a type manually.	Indicates the type of Ethernet packet to be captured. Common types include: Flow Control(88 08) LACP/OAM(88 09) LLDP(88 CC) LPT(E1 40) ARP(08 06) RARP(80 35) IPV4(08 00) IPV6(86 DD) MPLS(88 47)
WildCard	Number	Indicates the portion of the match value that packets need to match. The number of digits in the wildcard is the same as the number of digits in the match value. After the wildcard is converted to the binary format, digits 0 in it must match the corresponding digits in the match value, whereas digits 1 do not need to match.
