Cisco Catalyst switch C1200-24P-4X - REFRESH
CISCO REFRESH jsou repasované produkty, které společnost CISCO dodává s certifikací kvality, zárukou a servisní podporou odpovídající ekvivalentnímu novému produktu
Řada Cisco Catalyst 1200 je další generací cenově dostupných chytrých přepínačů, které kombinují vysoký výkon a spolehlivost s kompletní sadou funkcí, které potřebujete pro malé a středně velké podnikové sítě. Přepínače fungují na přizpůsobeném softwaru operačního systému Linux a poskytují flexibilní možnosti správy, komplexní možnosti zabezpečení a funkce statického směrování na 3. vrstvě, které daleko přesahují možnosti neřízeného nebo levného přepínače a to za nižší cenu než u plně spravovaných přepínačů. Když potřebujete spolehlivé řešení pro sdílení online zdrojů a připojení počítačů, telefonů a bezdrátových přístupových bodů, chytré přepínače Catalyst řady 1200 poskytují ideální řešení za dostupnou cenu.

IGMP querier Used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
Head-of-Line (HOL) blocking HOL blocking prevention
Loopback detection Provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP

Security Secure Sockets Layer (SSL) Encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch
SSH Protocol SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported.
IEEE 802.1X (authenticator role) RADIUS authentication, guest VLAN, single/multiple host mode, and single/multiple sessions
STP loopback guard Provides 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 a secure auto-configuration. 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 systems Trustworthy 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])
