Cisco BS250-8T-2G

The CBS250-8T-E-2G is a versatile network switch with 8 Gigabit Ethernet ports and 2 additional Gigabit Ethernet ports. It's designed for enhanced networking needs and offers robust features for efficient data management and connectivity.

CBS250-8T-E-2G Specification
Capacity in millions of packets per second (mpps) (64-byte packets)14.88
Switching capacity in gigabits per second (Gbps)20
Total system ports10 Gigabit Ethernet
RJ-45 ports8 Gigabit Ethernet
Packet buffer1.5 MB
Unit dimensions (W x D x H)268 x 185 x 44 mm (10.56 x 7.28 x 1.73 in)
Layer 2 switching
VLANSupport for up to 255 active VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN
Voice VLANVoice traffic is automatically assigned to a voice-specific VLAN and treated
with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP)
delivers networkwide zero-touch deployment of voice endpoints and
call control devices
Layer 3 routing
IPv4 routingWire-speed routing of IPv4 packets
Up to 32 static routes and up to 16 IP interfaces
IPv6 routingWire-speed routing of IPv6 packets
Layer 3 interfaceConfiguration of Layer 3 interface on physical port, LAG, VLAN
interface, or loopback interface
Secure Sockets Layer (SSL)SSL encrypts all HTTPS traffic, allowing secure access to the
browser-based management GUI in the switch
Secure Shell (SSH) ProtocolSSH is a secure replacement for Telnet traffic. Secure Copy (SCP)
also uses SSH. SSH v1 and v2 are supported.
IEEE 802.1X (authenticator role)Remote Authentication Dial-In User Service (RADIUS) authentication,
guest VLAN, single/multiple host mode, and single/multiple sessions
STP loopback guardProvides additional protection against Layer 2 forwarding loops (STP loops)
Secure Core Technology (SCT)Ensures 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, and so on)
securely on the switch, populating this data to other devices,
and secure autoconfig.
Access to view the sensitive data as plain text or encrypted is provided according
to the user-configured access level and the access method of the user
Trustworthy systemsTrustworthy systems provide a highly secure foundation for Cisco products
Run-time defenses (Executable Space Protection [X-Space], Address Space
Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])
Port securityAbility to lock source MAC addresses to ports and limit the number of
learned MAC addresses
RADIUSSupports RADIUS authentication for management access.
Switch functions as a client.
Storm controlBroadcast, multicast, and unknown unicast
DoS preventionDenial-of-Service (DoS) attack prevention
Multiple user privilege levels in CLILevel 1, 7, and 15 privilege levels
Access Control Lists (ACLs)Support for up to 512 rules
Drop or rate limit based on source and destination MAC, VLAN ID or IPv4
or IPv6 address,
IPv6 flow label, protocol, port, Differentiated Services Code Point

TCP/UDP source and destination ports, 802.1p priority, Ethernet type, I
nternet Control Message Protocol (ICMP) packets,
IGMP packets, TCP flag; ACL can be applied on both ingress
and egress sides
Time-based ACLs supported
