Data Sheet
The Cisco 500X models provide an additional layer of resiliency with support for the Virtual Router
Redundancy Protocol (VRRP). VRRP lets you extend the same resiliency that stacking provides for
individual switches to complete network domains. By running VRRP between two stacks, you can instantly
cut over from one stack to another in the event of a problem, and continue operating even after a failure.
The Cisco 500 Series also supports dual images, allowing you to perform software upgrades without
having to take the network offline or worry about the network going down during the upgrade.
Simplified IT Operation
Cisco 500 Series switches help optimize your IT operations with built-in features that simplify and
streamline day-to-day network operation:
●
True stacking allows you to troubleshoot, configure, and manage multiple physical switches as a
single entity.
●
Unlike other stacking switches that require uniform configurations, the Cisco 500 Series allows you to
mix Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet models in a single stack, providing total
flexibility without sacrificing manageability.
●
Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches
within a category support the same feature set – making it easier to manage and support all switches
across the network.
True Stacking
Some switches claim to support stacking but in practice support only “clustering” – meaning that each
switch must still be managed and configured individually. Cisco 500 Series switches provide true stacking
capability, allowing you to configure, manage, and troubleshoot all switches in a stack as a single unit,
with a single IP address.
A true stack delivers a unified data and control plane, in addition to management plane, providing
flexibility, scalability, and ease of use since the stack of units operate as a single entity constituting all the
ports of the stack members. This capability can radically reduce complexity in a growing network
environment while improving the resiliency and availability of network applications. True stacking also
provides other cost savings and administrative benefits through features such as cross-stack QoS,
VLANs, and port mirroring, which clustered switches can’t support.
Strong Security
Cisco 500 Series switches provide the advanced security features you need to protect your business data
and keep unauthorized users off the network:
●
Embedded Secure Sockets Layer (SSL) encryption protects management data traveling to and from
the switch.
●
Extensive access control lists (ACLs) restrict sensitive portions of the network to keep out
unauthorized users and guard against network attacks.
●
Guest VLANs let you provide Internet connectivity to nonemployee users while isolating critical
business services from guest traffic.
●
Support for advanced network security applications such as IEEE 802.1X port security tightly limits
access to specific segments of your network.
