By having multiple control plane protocols like OSPF or
MPLS rely on BFD to detect forwarding plane connectivity
failures, network operators can benefit from simpler
network profiling and planning, and consistent and
predictable re-convergence times.
MPLS
On the X670-G2 series switches MPLS can be enabled, if
needed, by way of an optional feature pack. MPLS provides
the ability to implement trac engineering and multi-
service networks, and improve network resiliency. The
MPLS protocol suite provides the ability to deploy services
based on L2VPNS (VPLS/VPWS), BGP-based L3VPNS; LSP
Establishment based on LDP, RSVP-TE, Static provisioning;
Integrated OAM tools like VCCV, BFD and CFM; And MPLS
Fast Reroute to support rapid local convergence around
network failures.
High Availability Network
Protocols
Ethernet Automatic Protection Switching (EAPS)
EAPS allows the IP network to provide the level of resiliency
and uptime that users expect from their traditional voice
network. EAPS is more adaptable than Spanning Tree or
Rapid Spanning Tree protocols and can achieve sub-second
recovery that delivers consistent failover regardless of the
number of VLANs, network nodes or network topology in
Extreme Networks-recommended configurations.
EAPS functionality increases network recovery time, which
results in significant reduction in Voice-over IP call drop
rates and improvement in digital video performance in
supported solution configurations.
Spanning Tree/RAPID Spanning Tree Protocols
The X670-G2 supports Spanning Tree (802.1D), Per VLAN
Spanning Tree (PVST+), Rapid Spanning Tree (802.1w) and
Multiple Instances of Spanning Tree (802.1s) protocols for
Layer 2 resiliency.
Software-Enhances Availability
Software-enhanced availability allows users to remain
connected to the network even if part of the network
infrastructure is down. The X670-G2 continuously checks
for problems in the uplink connections using advanced
Layer 3 protocols such as OSPF, VRRP and Extreme
Standby Router Protocol (ESRP, supported in Layer 2 or
Layer 3), and dynamically routes trac around the problem.
Equal Cost Multipath
Equal Cost Multipath (ECMP) routing allows uplinks to be
load balanced for performance and cost savings while
also supporting redundant failover. If an uplink fails, trac
is automatically routed to the remaining uplinks and
connectivity is maintained.
Link Aggregation (802.3AD)
Link aggregation allows trunking of up to 32 links on a
single logical connection, for up to 320 Gbps of redundant
bandwidth per logical connection.
Multi-Switch LAG (M-LAG)
M-LAG can address bandwidth limitations and improve
network resiliency, in part by routing network trac around
bottlenecks, reducing the risks of a single point of failure,
and allowing load balancing across multiple switches.
Hardware Redundancy
X670-G2 series switches support a dual redundant AC/DC
power supply to provide high availability. The power supply
can be hot-swapped and replaced should it fail. Summit
X670-G2 also supports standardized N+1 redundant hot-
swappable fan units.
Robust IP and MAC Security
Framework
Media Access Control (MAC) Lockdown
MAC security allows the lockdown of a port to a given
MAC address and limiting the number of MAC addresses
on a port. This capability can be used to dedicate ports to
specific hosts or devices such as VoIP phones or printers
and avoid abuse of the port—a capability that can be
especially useful in environments such as hotels. In addition,
an aging timer can be configured for the MAC lockdown,
protecting the network from the eects of attacks using
(often rapidly) changing MAC addresses.
IP Security
ExtremeXOS IP security framework helps protect the
network infrastructure, network services such as DHCP and
DNS and host computers from spoofing and man-in-the-
middle attacks. It also protects the network from statically
configured and/or spoofed IP addresses and builds
an external trusted database of MAC/IP/port bindings
providing the trac’s source from a specific address for
immediate defense.
