Memory and Microcode Requirements for Release 11.3

Some software image sizes exceed 4 MB and, when compressed, exceed 2 MB. Also, some systems require more than 1 MB of main system memory for data structure tables.

For Cisco routers to take advantage of the Release 11.3 features, you must upgrade the code or main system memory as listed in Table 22. Some platforms have specific chip or architecture requirements that affect what can be upgraded and in what increments.

Microcode Software

Table 23 lists the current microcode versions for the Cisco 7500/RSP series. This series includes the Cisco 7000 equipped with the RSP7000 processor, the Cisco 7010 equipped with the RSP7000 processor, and the Cisco 7500 series routers. Note that microcode software images are bundled with the system software image—with the exception of the Channel Interface Processor (CIP) microcode (all system software images) and Versatile Interface Processor (VIP) microcode (certain system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards. Versatile Interface Processor (VIP and VIP2) microcode is bundled into all Cisco 7500 series feature sets listed in Table 22.

Note The Cisco 7000 series previously included the Cisco 7000 and 7010. These products are not supported in Cisco IOS Release 11.3. The Cisco 7000 series now includes the Cisco 7000 equipped with the RSP7000 processor and the Cisco 7010 equipped with the RSP7000 processor. For more information regarding this change, see the "Important Notes" section in this release note.

Channel Interface Processor (CIP) Microcode

Beginning with Cisco IOS Release 11.1, the CIP microcode is no longer bundled with the Cisco IOS software image. You must have at least 8 MB RAM installed on your CIP card to use the IBM channel attach features in Cisco IOS Release 11.1 and later. See the "Important Notes" section for more information about CIP microcode.

Modification

AIP Microcode Version 20.13 fixes the following:

The AIP does not show packets dropped due to traffic shaping. [CSCdi72246]

Ethernet Interface Processor (EIP) Microcode Revision Summary

EIP Microcode Version 20.3

Modification

EIP Microcode Version 20.3 fixes the following:

A bad R4600 processor causes router crashes with errors such as XBUFHDR errors, INVRTN errors, and GETBUF errors. [CSCdi75404]

Fast Ethernet Interface Processor (FEIP) Microcode Revision Summary

FEIP Microcode Version 20.6

Modification

FEIP Microcode Version 20.6 fixes the following:

Enabling FEIP in RP/SP 7000 causes the error message "CBUS-3-INITERR with Error (8021)." [CSCdj14743]

FEIP Microcode Version 20.7

Modification

FEIP Microcode Version 20.7 fixes the following:

FEIP-FX unable to detect TX fiber loss. [CSCdk03855]
VIP PA-FE-FX will not drop the link when the port shuts down AND breaks the EtherChannel. [CSCdk20683]

FDDI Interface Processor (FIP) Microcode Revision Summary

FIP Microcode Version 20.3

Modification

FIP Microcode Version 20.3 was never released.

FIP Microcode Version 20.4

Modification

FIP Microcode Version 20.4 fixes the following:

Online insertion and removal (OIR) of an interface processor in an RSP-based Cisco 7000 or Cisco 7500 router may result in multiple interfaces dropping a large number of incoming packets after the OIR. [CSCdk07259]

Fast Serial Interface Processor (FSIP) Microcode Revision Summary

FSIP Microcode Version 20.7

Modification

FSIP Microcode Version 20.7 fixes the following:

The "CBUS-3-CMDTIMEOUT" error causes FSIP to vanish. [CSCdj00013]

FSIP Microcode Version 20.8

Modification

FSIP Microcode Version 20.8 fixes the following:

On Cisco 7500 RSP platforms, FSIP serial interfaces may display the following panic messages on the RSP console:

: %RSP-3-IP_PANIC: Panic: Serial12/2 800003E8 00000120 0000800D 0000534C %DBUS-3-CXBUSERR: Slot 12, CBus Error %RSP-3-RESTART: cbus complex
: If the string "0000800D" is included in the panic message, the problem is related to this bug. The workaround is to load a new image that contains the fix for this bug. [CSCdi78086]

FSIP Microcode Version 20.9

Modification

FSIP Microcode Version 20.9 fixes the following:

An overrun/drop may be seen on serial interfaces on a FSIP on Cisco 7500 series. Issuing the shutdown and no shutdown commands will not clear this condition; neither will issuing the clear interface command.

: A workaround is to issue a command that will cause a "cbus complex" restart. As an example, change the MTU size and then change it back to your proper configuration. This example is shown below (assuming the MTU default was 1500):

interface s 1/0
mtu 8000        ! to cause a cbus complex restart
mtu 1500        ! change back to the proper value

HSSI Interface Processor (HIP) Microcode Revision Summary

HIP Microcode Version 20.2

Modification

HIP Microcode Version 20.2 fixes the following:

When HIP is in the router, OIR of any card causes problems. [CSCdj21227]

MultiChannel Interface Processor (MIP) Microcode Revision Summary

MIP Microcode Version 22.3

Modification

MIP Microcode Version 22.3 fixes the following:

A remote loop on a channelized T1 interface could stay looped. [CSCdj19606]

Token Ring Interface Processor (TRIP) Microcode Revision Summary

TRIP Microcode Version 20.1

Modifications

TRIP Microcode Version 20.1 fixes the following:

A SpyGlass problem causes the command queue to the Spyglass to overflow. The symptom of this problem is a "ctrucheck" at location 0x925 in trip10-3.
The DMA engine appears to "clock in" the memd address an extra time or increment the memd address an extra time. The obvious symptom is an "800E" (output stuck).
With transmit frames, the prototype Access Control byte is invalid (bit 0x10 is set).

TRIP Microcode Version 20.2

Modification

TRIP Microcode Version 20.2 fixes the following:

Online insertion and removal (OIR) of an interface processor in an RSP-based Cisco 7000 or Cisco 7500 router may result in multiple interfaces dropping a large number of incoming packets after the OIR. [CSCdk07259]
