Powerful service processing capabilities
S7700 supports distributed Layer 2/Layer 3 MPLS VPN functions,
including MPLS, VPLS, HVPLS, and VLL, implementing VPN access for
The S7700 supports various Layer 2 and Layer 3 multicast protocols such as PIM SM, PIM DM, PIM SSM, MLD, and IGMP snooping. It can provide enterprises with multi-terminal high definition video surveillance and video conferencing services.
Carrier-class reliability and visual fault diagnosis
The S7700 provides redundancy backup for key components, including switch routing units, power supply units, and fans, all of which are hot swappable. This provides carrier class reliability with 99.999% (five 9s).
Enhanced QoS mechanism, improving the voice and video experience
The S7700 supports hardware-based low delay queues for multicast packets so that the video service can be processed with high priority and low delay. This feature guarantees the high quality of key services in an enterprise, such as video conference and surveillance.
High performance in IPv6 service processing, realizing smooth transition from IPv4 to IPv6
the hardware platform and software platform of the S7700 support IPv6.
The S7700 has earned the IPv6 Ready Phase 2 (Gold) designation.
The S7700 supports IPv4/IPv6 dual stack, various tunneling technologies, IPv6 static routing, RIPng, OSPFv3, BGP+, IS-ISv6, and IPv6 multicast. These features meet the demand for IPv6 networking and combined IPv4 and IPv6 networking.
Comprehensive security mechanisms, defending enterprises against internal and external security threats
S7700 comes equipped with an integrated firewall card and supports
virtual firewalls and NAT multi-instance, allowing multiple VPN
customers to share the same firewall. Its application-layer packet
filtering technology detects and filters application layer packets
according to preset rules.
The S7700 is the industry leader in integrated security solutions. It supports 1K CPU queues and uses a 2-level CPU protection mechanism, separating the data plane from the control plane. Additionally, the S7700 defends against DoS attacks, prevents unauthorized access, and prevents control plane overloading.
Wireless AC boards, meeting mobile office requirements
The S7700's AC board supports multiple authentication methods, including 802.1x authentication, MAC address authentication, Portal authentication, and WAPI authentication. These authentication methods meet the requirements of users who use different types of STAs and require different security levels.
Innovative energy-saving chips, allowing intelligent power consumption control
S7700 supports Power over Ethernet (PoE) and uses different energy
management modes according to the powered device (PD) type, ensuring
flexible energy management.
The S7700 supports IEEE 802.3az Energy Efficient Ethernet and provides the low power idle mode for the PHY line card. If the link utilization is low, the S7700 switches to a lower speed or power PHY to reduce power consumption.
