Support encrypted WAN connectivity between distributed locations with a Cisco MSLA-C C1 SD-WAN VPN appliance. The C1 configuration is specified for a 1 Gbps VPN path, making it relevant where site-to-site encrypted traffic must be carried through an SD-WAN deployment. It is hardware for the WAN edge rather than a standalone Ethernet switch or wireless access point. Place the appliance at a branch, remote office, or other network edge where the SD-WAN architecture requires a VPN-capable endpoint. Its role is to participate in the encrypted overlay between connected locations while providing the C1 capacity profile. Network teams can use the 1 Gbps VPN figure when assessing whether this platform aligns with the expected encrypted WAN traffic level. Cisco CDMSLAC-C1-P-1G identifies the MSLA-C hardware configuration with the C1 and 1G VPN designation. Those identifiers matter when matching an appliance to an established SD-WAN design: the relevant distinction is the C1 configuration and its stated 1 Gbps VPN capability. Review the required WAN topology and encrypted traffic requirement before selecting the appliance.
