Supported Features

This section provides a list of some of the primary features supported by the SIP and SPA hardware and software.

Cisco 7600 SIP-200 and Cisco 7600 SIP-400 Features

The SIPs are carrier cards designed to process packets between different SPAs and the Catalyst 6500 Series switch switching fabric.

Online insertion and removal (OIR)

Supports up to four single-height or two double-height Shared Port Adaptors (SPAs).

Field Programmable Gate Array (FPGA) upgrade support

The SIPs support the standard FPD upgrade methods for the Catalyst 6500 Series switch. For more information about FPD support, see Chapter 31, "Upgrading Field-Programmable Devices."

Restrictions


Note For other SIP-specific features and restrictions see also Chapter 3, "Overview of the SIPs and SSC"in this guide.


On a 2-port or 4-port Channelized T3 SPA, when one of the T3 ports is configured as a DS3 Clear Channel interface and the other T3s are configured with a large number (greater than or equal to 400) of low-bandwidth channels (NxDS0, N=1,2,3 or 4), the DS3 Clear Channel interface is not able to run at 100 percent DS3 line rate when those low-bandwidth channels are idle (not transmitting or receiving packets). This issue does not occur if those low-bandwidth channels are not idle.

On a 2-Port and 4-Port Channelized T3 SPA or 1-Port Channelized OC-3/STM-1 SPA, the maximum number of channels is limited to 1023 per SPA.

On a 2-Port and 4-Port Channelized T3 SPA or 1-Port Channelized OC-3/STM-1 SPA, the maximum number of FIFO buffers is 4096. The FIFO buffers are shared among the interfaces; how they are shared is determined by speed. If all the FIFO buffers have been assigned to existing interfaces, a new interface cannot be created, and the "%Insufficient FIFOs to create channel group" error message is seen. Table 14-1 provides FIFO allocation information.

To find the number of available FIFO buffers, use the show controller t3 command:

Router# show controller t3 3/0/0
 
T3 3/0/0 is up.
  Hardware is SPA-4XCT3/DS0
  IO FPGA version: 2.6, HDLC Framer version: 0
  T3/T1 Framer(1) version: 2, T3/T1 Framer(2) version: 2
  SUBRATE FPGA version: 1.4
  HDLC controller available FIFO buffers 3112

Displaying the SPA Hardware Type

To verify the SPA hardware type that is installed in your Catalyst 6500 Series switch, you can use the show diagbus command or the show interface command (once the interface has been configured). There are several other commands on the Catalyst 6500 Series switch that also provide SPA hardware information.

Table 14-2 shows the hardware description that appears in the show command output for each type of SPA that is supported on the Catalyst 6500 Series switch.
