Up to 20 redundant-port pairs are supported to increase link resiliency.
●
Inter-module redundancy is supported with one pair in a stack. The switching time is
●
approximately 1 second.
Link Aggregation Group (LAG) support of up to 7 trunks, with each trunk having up to 8 10/
●
100 links or 2 GB links, provides resiliency, load balancing, and bandwidth expansion.
LAG redundancy is supported through resiliency between two LAG groups.
●
Port mirroring of any switch port is supported.
●
RMON/SMON port statistics provide real-time top-down analysis of network traffic.
●
IP multicast filtering (snooping) filters multicast traffic to optimize network bandwidth.
●
Classification of ports as regular or valuable is supported so that if a link fails, notification is
●
generated for valuable ports only.
The L2 CAM table contains 16K MAC addresses.
●
Layer 3 features
Note:
An additional license is required for Layer 3 features.
Note:
Static, RIPv1, RIPv2, OSPF IP routing protocols are supported.
●
Equal cost routing is used for load balancing and redundancy.
●
Router redundancy (VRRP) is supported.
●
NetBIOS rebroadcasting is available for applications such as WINS that use broadcasting
●
but may need to also communicate with stations on other subnets or VLANs.
ICMP and ARP protocols are supported.
●
DHCP/BootP relay allows broadcast requests to be forwarded to servers.
●
Policy-based routing of packets provides enforcement of QoS and ACL rules.
●
The L3 CAM table contains 4K IP addresses.
●
Management
Access to the management interfaces are password-protected at three levels (read-only,
●
read-write access and supervisor) to prevent unauthorized configuration changes.
You can access to the Command Line Interface (CLI) in the following ways:
●
- Direct console or modem connection
- Telnet (up to five simultaneous connections) or SSHv2 (up to two simultaneous
connections) over the IP network
You can use TFTP for the download/upload of configuration files or the download of
●
firmware files
