Confused about ios version ending SE & SEE

[krunoslav.studak]

Hello,

can somebody please provide me with information about the difference between two 12.2 ios versions for a 3750 switch.

12.2.25-SEE4(ED)

12.2.46-SE(ED)

Both are the latest releases

What does the ending SE and SEE mean??

Hi,

Release 12.2SE :::

Cisco IOS Software functionality and hardware for mid-range and low-end Ethernet LAN switching for Enterprise access and distribution networks.

(25)SEE ::: Forms the individual release number.

IOS S Numbering :::

The releases within the IOS S family share a common code base from Cisco IOS Software Release 12.2S. On top of the common code base, additional software fixes and new software features are included in each version of Cisco IOS Software Releases 12.2SB, 12.2SX, 12.2SE, 12.2SG, and 12.2SR. After their inclusion, where applicable, the additional software fixes and new software features are propagated to other IOS S family members.
