1+1 LAG naming rules
...................................................................................................................................................................................................................................
The following considerations apply to proposed naming rules for Ethernet Link
Aggregations:
• Data Client purposes field keeps both the same range and syntax as in referred
document for aming Rule for 4G node
–
– L bits allow to decode the hierarchical level; L bits are set to 00 when an LAG
• Channel field has been removed from the LAG naming rule
• Hierarchical structure (with physical coordinates (rack, subrack, drawer, board))
inside 4G E naming rule with 00 T subfield is replaced from a flat structure
consisting of both Interface Type and Logical Interface Identifier field:
– Interface Type field is filled up with "hard-coded" IA A If Type value (161) for
– Logical Interface Identifier field is filled up with LAG logical identifier: up 256K
Example
• 31 30 29 28 | 27 26 25 24 23 22 21 20 19 18 | 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2
1 0
• 00 01 00 00 | 00 00 01 00 01 00 00 00 00 01 | LAG logical identifier
• Index of LAG x = 1115947008 (0x42840000) + x

B-2
aming rule for Ethernet Link Aggregation is identified from an "hard-coded"
value encoded in T subfield (equal to decimal 1), identifying an LAG as a logical
interface;
interface is created and are incremented for stacked interface over LAG interface
Ethernet Link Aggregation
Link Aggregation Groups are allowed to be supported "on per E basis."
