Cisco IOS Versions Affected

Systems configured with dual RSPs (HSA feature) are affected by CSCdk01707. The high system availability (HSA) feature is supported in all RSP images with a "v" listed in the feature set. Only the "v" images are deferred 1 and the remaining images without the "v" will be made available following the standard release process.

Because of the feature affected, the Cisco IOS software images listed in Table 2 are deferred (meaning, not posted on CCO or available through a new order) as of May 29, 1998. Existing orders will be issued with the fix for each Major Release3 stated in Table 3.

Notes:

1 - CAT5K RSM "v" images are not deferred because of the RSM not supporting dual processors.

2 - Cisco IOS rsp-p-mz images are not orderable. These images are available only through CCO online.

3 - 11.2P orders will be issues 11.2(12a)P images until 11.2(14)P is available.

4 - 11.1CT "v" images are not deferred due to 11.1CT's limited customer production use at this time.
