Layer 2 Switching

Spanning Tree Protocol

Standard 802.1d Spanning Tree Support.

Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default.

Multiple spanning tree instances, using 802.1s (MSTP). 16 instances are supported.

Port grouping/link aggregation

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

   Up to 8 groups

   Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG

VLAN

Support for up to 4096 VLANs simultaneously

Port-based and 802.1Q tag-based VLANs

MAC-based VLAN

Management VLAN

PVE (Private VLAN Edge), also known as Protected Port, with multiple uplinks

Guest VLAN

Unauthenticated VLAN

Protocol-based VLAN

CPE VLAN

Dynamic VLAN assignment via Radius server along with 802.1x client authentication

Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices.

Multicast TV VLAN

Continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons. This feature is also known as Multicast VLAN Registration (MVR).

Q-in-Q

VLANs transparently cross over a service provider network while isolating traffic among customers.

GVRP/GARP

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain.

DHCP Relay at Layer 2

Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82.

IGMP (versions 1, 2, and 3) snooping

Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 1000 multicast groups (source-specific multicasting is also supported).

IGMP querier

IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router.

HOL blocking

Head-of-line (HOL) blocking.

Jumbo Frames

Frames up to 10K in length.

Layer 3

IPv4 routing

Wire-speed routing of IPv4 packets

Up to 128 static routes and up to 128 IP interfaces

CIDR

Support for Classless Inter-Domain Routing

RIP v2 (on 550X)

Support for Routing Information Protocol version 2, for dynamic routing

VRRP (on 550X)

Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are supported. Up to 255 virtual routers are supported.

DHCP Relay at Layer 3

Relay of DHCP traffic across IP domains.

User Datagram Protocol (UDP) Relay

Relay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets.

Stacking

Hardware stack

Up to 200 ports managed as a single system with hardware failover.

High availability

Fast stack failover delivers minimal traffic loss.

Plug-and-play stacking configuration/management

Primary/backup for resilient stack control

Auto-numbering

Hot swap of units in stack

Ring and chain stacking options

Auto stacking port speed

Flexible stacking port options

High-speed stack interconnects

Cost-effective 10G copper and high-speed 10G Fiber interfaces.

Mixed stacking support

A stack can consist of a mix of ESW2 550X and SG500X models.

Security

SSH

SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.

SSL

Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch.

IEEE 802.1X
(Authenticator role)

RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode and single/multiple sessions

Supports time-based 802.1X

Dynamic VLAN assignment

STP BPDU Guard

A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops.

STP Root Guard

Prevents a port from being selected as a root port, effectively preventing bridges in the LAN segment connected to the port from being a root bridge. This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes.

DHCP snooping

Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server.

IP Source Guard (IPSG)

When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing.

Dynamic ARP Inspection (DAI)

The switch discards Address Resolution Protocol (ARP) packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks.

Secure Core Technology (SCT)

Helps ensure that the switch will receive and process management and protocol traffic no matter how much traffic is received.

Secure Sensitive Data (SSD)

A mechanism to manage sensitive data (such as passwords, keys, etc.) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user-configured access level and the access method of the user.

Layer 2 isolation (PVE) with community VLAN*

Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinks.

Port security

Ability to lock MAC addresses to ports, and limit the number of learned MAC addresses.

RADIUS/TACACS+

Supports RADIUS and TACACS authentication. Switch functions as a client.

RADIUS accounting

The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session.

Storm control

Broadcast, multicast, and unknown unicast.

DoS prevention

DoS attack prevention.

Congestion avoidance

A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization.

Multiple user privilege levels in CLI

Levels 1, 7, and 15 privilege levels.

ACLs

Support for up to 3000 rules on 550X series.

Drop or rate limit based on source and destination MAC, VLAN IDor IP address, protocol, port, DSCP/IP precedence, TCP/ User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (IGMP) packets, and TCP flag.

Cisco Discovery Protocol

The switch advertises itself using the Cisco Discovery Protocol (CDP). It also learns the connected device and its characteristics via CDP.
