In the fast-paced world of SD-WAN, cloud-native networking, and 400G interfaces, it’s easy to overlook the "gray boxes" gathering dust in the back of the server room. But if you’ve got a Cisco Catalyst 3560 series switch running c3560-ipservicesk9-mz.150-2.se11.bin

ip vrf CUSTOMER_A rd 65000:100 route-target export 65000:100 route-target import 65000:100 ! interface GigabitEthernet0/10 ip vrf forwarding CUSTOMER_A ip address 10.1.1.1 255.255.255.0 ! router bgp 65000 address-family ipv4 vrf CUSTOMER_A neighbor 10.1.1.2 remote-as 65001 C3560-ipservicesk9-mz.150-2.se11.bin

Licensing and legal considerations

k9

The suffix indicates cryptographic support – SSH, SSL, PKI, and encrypted passwords. This is mandatory for any network requiring secure management. In the fast-paced world of SD-WAN, cloud-native networking,

• Layer 3 Routing: Unlike IP Base, this image provides full Layer 3 routing capabilities, including OSPF, EIGRP, and BGP. This makes the switch capable of acting as a Layer 3 distribution or core switch in smaller enterprise networks.
• Advanced Protocols: It supports advanced features like Policy-Based Routing (PBR), VRF-Lite, and advanced QoS mechanisms.
• Encryption (k9): The inclusion of the k9 designation is critical for modern network security. It allows for the use of SSHv2 (Secure Shell) for remote management, SNMPv3 for secure monitoring, and encrypted VPN tunnels (if the hardware supports it), ensuring compliance with security best practices.
