This image contains known unpatched vulnerabilities. It should only be used in air-gapped, legacy, or lab environments. 10. Conclusion c3560-ipservicesk9-mz.150-2.se11.bin represents the zenith of classic IOS for the Catalyst 3560 platform. It is stable, feature-rich (including full BGP on a $500 switch – astonishing for its time), and was trusted in tens of thousands of wiring closets worldwide.
This file is one of the most iconic and widely deployed software releases for the now-legacy, but once-ubiquitous, Cisco Catalyst 3560 series switches. 1. Executive Summary Filename: c3560-ipservicesk9-mz.150-2.se11.bin Platform: Cisco Catalyst 3560 (Standard 10/100, 3560G Gigabit, and 3560E models) IOS Version: 15.0(2)SE11 Feature Set: IP Services (IPSERVICESK9) File Type: Cisco IOS (Internetwork Operating System) binary image C3560-ipservicesk9-mz.150-2.se11.bin

This image represents the for the Catalyst 3560 series on IOS 15.0. It is a maintenance release (SE11) that fixes numerous bugs and security vulnerabilities without introducing new major features. It is the recommended "golden image" for the 3560 platform before it entered End-of-Life (EoL). 2. Nomenclature Breakdown Cisco's image naming convention is dense with meaning. Here is the exact breakdown: Conclusion c3560-ipservicesk9-mz
| Token | Value | Meaning | | :--- | :--- | :--- | | | c3560 | Catalyst 3560 Series (Base, G, E, PoE variants) | | Feature | ipservicesk9 | IP Services feature set + K9 (AES/DES 3DES encryption) | | Memory Type | mz | m = runs from DRAM (not compressed to flash); z = zip compression | | IOS Major | 150 | IOS version 15.0. Indicates a major architectural shift from 12.2/12.4 | | IOS Minor/Patch | 2 | 15.0(2) – The second major release of the 15.0 train | | Maintenance | se11 | s = Service provider / extended maintenance; e = Enterprise; 11 = 11th maintenance rebuild | | Extension | .bin | Binary executable. Also contains a mini-FS (file system) at boot | Note on k9 : This enables cryptographic features: SSHv2, SNMPv3 encryption, PKI, and IKE/IPSEC for management traffic. It does not enable IPsec data-plane routing (that requires a router IOS). On a switch, K9 is primarily for secure management. 3. Feature Set: IP Services (IPSERVICESK9) The ipservicesk9 image is the full feature set for the 3560. It includes everything from the lower tiers ( ipbasek9 , ipbasek9 + ipvoice ) plus:
| Feature Category | Included Capabilities | | :--- | :--- | | | OSPF, EIGRP, BGP, RIP v1/v2, IS-IS, Static, Policy Based Routing (PBR) | | Multicast | PIM SM/SSM/DM, IGMP v1/v2/v3, MSDP | | QoS | Advanced classification, policing (single/dual-rate), shaping, WRED, Auto-QoS | | Security | 802.1x with MAB, DHCP Snooping, DAI, IP Source Guard, ACLs (RACL, VACL, PACL), Port Security, Storm Control, BPDU Guard/Root Guard | | High Availability | StackWise (multiple units), FlexLink, Cross-Stack EtherChannel | | IPv6 | Full IPv6 routing, OSPFv3, EIGRPv6, MLD snooping, IPv6 ACLs | | Management | SNMP v1/2c/3, SSHv2, HTTP/HTTPS, RADIUS, TACACS+, NetFlow (limited), Syslog, SPAN/RSPAN |
