EDP is a SNAP encapsulated frame. The top level looks like this:
|
|
The top level format is like this:
|
|
[ SNAP header ] [ EDP header] [ TLV 0 ] [ TLV 1 ] ... [ TLV N ]
|
|
|
|
Header format:
|
|
1 octet: EDP version
|
|
1 octet: reserved
|
|
2 octets: length
|
|
2 octets: checksum
|
|
2 octets: sequence #
|
|
8 octets: device id (currently 2 0 octets followed by system mac address)
|
|
|
|
TLV stands for Type, Length, Value.
|
|
Format of a TLV entry:
|
|
marker ( 1 octet): Hex 99
|
|
type ( 1 octet):
|
|
The following types are used:
|
|
Null (used as an end signal): 0
|
|
Display (Mib II display string): 1
|
|
Info (Basic system information): 2
|
|
Vlan Info : 5
|
|
ESRP : 8
|
|
Length: Length of subsequent data(2 octets)
|
|
Value: Length octets of data.
|
|
|
|
Format for Info TLV:
|
|
two octets: originating slot #
|
|
two octets: originating port #
|
|
two octets: Virtual Chassis Id (If originating port is connected to a virtual chassis).
|
|
six octets: reserved
|
|
four octets: software version
|
|
16 octets: Virtual Chassis Id connections
|
|
|
|
Format for Vlan info:
|
|
octet 0: Flags (bit 8 = 1 means this vlan has an IP interface)
|
|
octets 1,2,3: reserved.
|
|
octets 4,5: vlan Id (0 if untagged)
|
|
octets 6,7: reserved.
|
|
octets 8 - 11: Vlan IP address.
|
|
Rest of value: VLAN name.
|
|
|
|
Display string is merely length octets of the MIBII display string.
|
|
|
|
These are the structures you will see most often in EDP frames.
