What to do next
Users cannot use the console or Telnet to view the BOF or execute the BOF commands on an IMM-only
node. To update the VC parameters associated with the IMM-only node, users should reboot the node,
interrupt the boot process, and use the menu prompts displayed in the boot loader context.
5.2.4 Configuring an IMM-only node in a VC
To configure an IMM-only node in the VC, use the command config>system>vc-stack-node slot-number
mac-address mac-address [create].
An IMM-only node in a VC is identified by its slot-number and its MAC address. The slot number assigned
to the node can be an arbitrary number from 1 to 8. It is used in service provisioning to identify ports on
a VC member node, and on service objects on those ports. The port on a VC member node is identified
using the format slot-id/1/port-id;sap-id. For example, port 20 on the front panel of a VC member node in
slot 4 with a SAP ID of 300 is identified as 4/1/20:300.
Slot numbers are unique to each VC, which are identified by their vc-stack-name, and can be reused
across different VCs. Software ensures the uniqueness of the slot number in each VC by raising an error if
two nodes in the same VC are assigned the same slot number.
When an IMM-only node boots up, it uses the MAC address and slot number received in the VC discovery
messages sent by the CPM node to discover VC configuration information. The MAC address used for VC
configuration is the chassis MAC address printed on the label of the node. If it does not match the MAC
address retrieved from the EEPROM, the node will not be able use the VC configuration information. For
CPM-IMM nodes, this will result in boot failure. The IMM-only nodes will wait indefinitely for a VC discovery
message with the correct MAC address from the CPM-IMM node, or until the operator removes the node
from the VC by disconnecting its stacking ports.
5.2.5 Provisioning the card type for all nodes in a VC
When the TiMOS image boots up on the CPM-IMM nodes and the IMM-only node, users must provision
the card type on each node so that the software knows which hardware platforms are members of the VC.
The software can then determine the logical IMM types, which are the slots of the VC. Provisioning the
card type is a mandatory step in the bootup process for all nodes of the VC in order for the nodes/cards to
be fully functional. Use the following CLI command:
A:Dut-A# configure card 1 card-type
- card-type <card-type>
- no card-type
<card-type> : sas-sx-24sfp-4sfpp | sas-sx-48sfp-4sfpp | sas-sx-24t-
4sfpp | sas-sx-48t-4sfpp | sas-s-24sfp-4sfpp|sas-s-48sfp-4sfpp|sas-s-24t-4sfpp|sas-
s-48t-4sfpp
The card type can be preprovisioned and allows for preprovisioning of services. If the software-determined
card type does not match the configured card type for the slot number, a provisioning mismatch error is
logged. The software determines the card type by reading the information on the EEPROM of the platform.
The following table lists the supported card types associated with the 7210 SAS-Sx 1/10GE platform.
