VadaTech UTC002 10 GbE to 1 GbE mode
CoBo (and its FRU) is designed to have two physically independent 1GbE connections to AMC PORT0 and PORT4. VadaTech 10GbE switch (connected to AMCs PORT 4) inside UTC002 has to be configured to allow its 10GbE ports to accept 1GbE (only) connections. Therefore, in order for CoBo 1GbE connection (on PORT4) to work on VadaTech's UTC002 10GbE switch the following has to be performed (once):
If the following is not performed CoBo physical GbE link on PORT4 will fail.
NOTE: Default username and password is root
1- Connect your workstation (must have 192.168.40.x IP) to GbE0 or GbE1 on UTC002 frontpanel 2- ssh to MCH
ssh root@192.168.40.250
3- use the serial link to connect to VadaTech UTC002 Broadcom 10gbe switch, at the prompt type:
vt set rs232sel=0 export TERM=vt100; stty rows 1024 cols 80 minicom -w -o ttyS2
4- press enter to see login prompt
10GbE_Mgmt login:
4- edit /etc/rc.d/rc.local
vi /etc/rc.d/rc.local
5- append the following:
axel_1g_port 15 # (AMC 01) axel_1g_port 7 # (AMC 02) axel_1g_port 0 # (AMC 03) axel_1g_port 8 # (AMC 04) axel_1g_port 16 # (AMC 05) axel_1g_port 13 # (AMC 06) axel_1g_port 19 # (AMC 07) axel_1g_port 11 # (AMC 08) axel_1g_port 3 # (AMC 09) axel_1g_port 4 # (AMC 10) axel_1g_port 12 # (AMC 11) axel_1g_port 17 # (AMC 12)
6- save /etc/rc.d/rc.local
7- shutdown the whole chassis and restart it back again.
8- The operating system (or temac driver) running on CoBo has to switch off auto-negotiation on that ethernet interface. For example, on Linux I patched the kernel to do that. See :cobo.patch
9- To physically isolate the 10GbE and the 1GbE switches. Disconnect the 1GbE switch from the 10GbE by typing:
A- login to 10GbE switch using ssh or rs232 (as indicated above) B- when you see the prompt type cli C- in CLI type set-port-state 16 disable D- then type save-config
