TELL1 Aggregation Switch Configuration
- Currently, the TELL1 boards are connected to sw-daq-01 (the E1200 Force 10) through two aggregation switches, sw-agg-01 and sw-agg-02.
- Note: The aggregation switches are used as switches, and not routers.
- For assigning IP addresses to the TELL1s, please refer to this page: https://twiki.cern.ch/twiki/bin/view/LHCb/TELL1IPRanges
- Configuration for both switches is identical. The VLAN-port assignment is given below
VLAN |
Ports |
10 |
A2,A3,A4,A5,A21 |
11 |
A6,A7,A8,A9,A10,A22 |
12 |
A11,A12,A13,A14,A15,A23 |
13 |
A16,A17,A18,A19,A20,A24 |
14 |
B1,B2,B3,B4,B5,B21 |
15 |
B6,B7,B8,B9,B10,B22 |
16 |
B11,B12,B13,B14,B15,B23 |
17 |
B16,B17,B18,B19,B20,B24 |
18 |
C1,C2,C3,C4,C5,C21 |
19 |
C6,C7,C8,C9,C10,C22 |
20 |
C11,C12,C13,C14,C15,C23 |
21 |
C16,C17,C18,C19,C20,C24 |
22 |
D1,D2,D3,D4,D5,D21 |
23 |
D6,D7,D8,D9,D10,D22 |
24 |
D11,D12,D13,D14,D15,D23 |
25 |
D16,D17,D18,D19,D20,D24 |
The basic idea is to connect ports 21, 22, 23 and 24 on each switch module to sw-daq-01, and pair them up with 5 ports with links from the TELL1s.
NOTE: VLAN 10 is the exception (in both switches), since A1 is used as the controls link to the switch.
