The following BOF configuration guidelines apply to these platforms:
When the chassis-role parameter for the node is set to satellite, DHCP requests are sent out of the following ports:
ports 1/1/25, 1/1/26 (10GE ports) on the 24-port 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Mxp variants
ports 1/1/49, 1/1/50 (10GE ports) on the 48-port 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE variants
ports 1/1/65, 1/1/66 (100GE ports), and ports 1/1/1, 1/1/2 (which are 10GE ports) on the 7210 SAS-Sx 10/100GE 64SFP+ 4CFP4 variant
ports 1/1/c1/1 and 1/1/c2/1, and 10 GE ports 1/1/1 and 1/1/2 on the 7210 SAS-Sx 10/100GE 64SFP+ 4QSFP28 variant
The boot loader continuously iterates over the previously mentioned ports, sending out DHCP requests until the boot loader receives a response from the host.
When the chassis-role parameter for the node is set to standalone, DHCP requests are sent out of the following ports:
ports 1/1/27, 1/1/28 (10GE ports) and ports 1/1/1, 1/1/2 (1GE ports) on the 24-port 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Mxp variants
ports 1/1/51, 1/1/52 (10GE ports) and ports 1/1/1, 1/1/2 (1GE ports) on the 48-port 7210 SAS-Sx/S 1/10GE, and 7210 SAS-S 1/10GE variants
ports 1/1/67, 1/1/68 (100GE ports) and ports 1/1/1, 1/1/2 (10GE ports) on the 7210 SAS-Sx 10/100GE 64SFP+ 4CFP4 variant
ports 1/1/c3/1 and 1/1/c4/1, and 10 GE ports 1/1/1 and 1/1/2 on the 7210 SAS-Sx 10/100GE 64SFP+ 4QSFP28 variant
In addition, the boot loader will attempt to load the TiMOS image (both.tim) from the local flash if auto-init fails (that is, no responses were received from the DHCP server).
When the node is shipped from the factory (with the chassis-role set to factory-default) and powered up for the first time, the node sends out DHCP requests on the following ports:
10GE ports 1/1/25, 1/1/26, 1/1/27, and 1/1/28 on the 24-port 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Mxp
10GE ports 1/1/49, 1/1/50, 1/1/51 and 1/1/52 on the 48-port 7210 SAS-Sx 1/10GE and 7210 SAS-S 1/10GE
the first two 1GE ports, 1/1/1 and 1/1/2, on all 7210 SAS-Sx/S 1/10GE and 7210 SAS-Mxp variants
On a 7210 SAS-Sx 10/100GE CFP4 platform shipped from the factory, the DHCP requests are sent out of the first two 10GE ports (1/1/1 and 1/1/2) and all 100GE ports (1/1/65, 1/1/66, 1/1/67, and 1/1/68).
On a 7210 SAS-Sx 10/100GE 64SFP+ 4QSFP28 variant, the DHCP requests are sent out of ports 1/1/c1/1, 1/1/c2/1, 1/1/c3/1, and 1/1/c4/1, and the first two 10 GE ports (1/1/1 and 1/1/2). To change this, connect to the console and modify the chassis-role parameter value to either satellite or standalone, as required. After the chassis-role parameter is updated, the node attempts autoinit to retrieve the BOF.
