Cisco Router and SDM


Slide 3

SDM is an embedded web-based management tool. Provides intelligent wizards to enable quicker and easier deployments, and does not require knowledge of Cisco IOS CLI or security expertise. Contains tools for more advanced users: ACL editor VPN crypto map editor Cisco IOS CLI preview What Is Cisco SDM?


Slide 4

Cisco SDM Features Smart wizards for these frequent router and security configuration issues: Avoid misconfigurations with integrated routing and security Secure the existing network infrastructure easily and cost-effectively Uses Cisco TAC- and ICSA-recommended security configurations Startup wizard, one-step router lockdown, policy-based firewall and ACL management (firewall policy), one-step VPN (site-to-site), and inline IPS Guides untrained users through workflow

Site-to-Site VPN Components


Slide 7

Site-to-Site VPN Components VPN wizards use two sources to create a VPN connection: User input during the step-by-step wizard process Preconfigured VPN components SDM provides some default VPN components: Two IKE policies IPsec transform set for Quick Setup wizard Other components are created by the VPN wizards. Some components (e.g., PKI) must be configured before the wizards can be used.

Quick Setup (Cont.)


Slide 14

Step-by-Step Setup Multiple steps are used to configure the VPN connection: Defining connection settings: Outside interface, peer address, authentication credentials Defining IKE proposals: Priority, encryption algorithm, HMAC, authentication type, Diffie-Hellman group, lifetime Defining IPsec transform sets: Encryption algorithm, HMAC, mode of operation, compression Defining traffic to protect: Single source and destination subnets, ACL Reviewing and completing the configuration

Slide 33

Summary SDM is a GUI and one of its features is to provide simplified management of security mechanisms on Cisco IOS routers. SDM can manage various types of site-to-site VPNs. SDM can be used to implement a simple site-to-site VPN in three ways: Using the quick setup wizard Using the step-by-step wizard Configuring individual VPN components Upon completing the configuration, the SDM converts the configuration into the Cisco IOS CLI format.
