Fabric topology for receive side links.

Fabric topology for transmit side links.

State of the fabric link:

• RESET—Link between the SIB and the FPC/DPC is powered down on purpose. This is done in all non-dual Packet Forwarding Engine–based boards.

• UP—Link between the SIB and the FPC/DCP is up and running.

• DOWN—Link between the SIB and the FPC/DCP is powered down.

• FAULT—The SIB is in the alarmed state, in which the SIB’s plane is not operational for one or more of the following reasons:

  • On-board F-chip is not operational.

  • Fiber-optic connector faults.

  • FPC connector faults.

  • SIB midplane connector faults.

  Note:

  The following state descriptions are applicable only to PTX Series Packet Transport Routers.

• OK—The link between the SIB and the FPC is operational.

• Down—The link between the SIB and the FPC is powered down.

• Error—The CCL link between the SIB and FPC is not operational for one or more of the following reasons:

  • FPC midplane connector failure.

  • SIB midplane connector failure.

  • CCL link CRC error.

State of the links from the F13 SIB to the LCC or vice-versa. Out-Links indicate Tx links. In-Links indicate an Rx link. The following additional fields are displayed for each SIB:

• VCSEL Status—Optical (VCSEL channel) link status for the corresponding electrical (HSL2) link. The states include:

  • OK—Optical signal power is good.

  • Error—Internal error.

  • LOS—Loss of Signal detected.

  • High Cur—The Tx Bias-current is higher than threshold on this channel. This is applicable only to Tx Channels.

  • Low Cur —The Tx Bias-current is lower than threshold on this channel. This is applicable only to Tx Channels.

• HSL2 Channel—HSL2 is the electrical link used to connect ASICs to the in-link and out-link. The channel number corresponds to the link and varies based on the ASIC or configuration.

• HSL2 Status —The status of the HSL2 Channel. Includes the following states:

• Up—Channel is up.

• Down—Channel is down.

• Reset—Channel has been reset.

• Fault—Channel has faults.
