Restrictions

This section provides a list of Cisco 7600 SIP-200 configuration 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 DS3 clear channel interface and the other T3s are configured with 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% DS3 line rate when those low bandwidth channels are idle (that is, 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. FIFO allocation information is provided in Table 16-1.

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

Note Effective from Cisco IOS Release 15.1(3)S and 12.2(33)SRE05, the SPA-1xCHOC12/DS0 boots up with admin down status and the original SPA status is restored after one second of the SPA bootup. Please wait for a second after the log message "SPA_OIR-6-ONLINECARD: SPA (SPA-1XCHOC12/DS0) online in subslot" is displayed, to configure the SPA.

Displaying the SPA Hardware Type

To verify the SPA hardware type that is installed in your Cisco 7600 series router, 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 Cisco 7600 series router that also provide SPA hardware information.

Table 16-2 shows the hardware description that appears in the show command output for each type of SPA that is supported on the Cisco 7600 series router.
