A VLAN access control list (VACL) provides access control for all packets that are bridged within a VLAN or that are routed into or out of a VLAN. Unlike regular Cisco IOS access control lists that are configured on router interfaces and applied on routed packets only, VACLs apply to all packets.
Cisco's IOS software maintains one IDB for each hardware interface in a particular Cisco switch or router and one IDB for each subinterface. The number of IDBs present in a system varies with the Cisco hardware platform type. Physical and logical interfaces on the switch will be referenced with either expanded or abbreviated port description names.
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
Cisco 2503 with top cover removed. The Cisco 2500 series routers are a series of 19" rack mount access routers typically used to connect Ethernet or Token Ring networks via ISDN or leased serial connections (i.e. Frame Relay, T1 etc.). The routers are based on a Motorola 68EC030 CISC processor. [1]
Access Layer - 'Routed Access' Configuration (in lieu of Spanning Tree) SVIs advantages include: Much faster than router-on-a-stick, because everything is hardware-switched and routed. No need for external links from the switch to the router for routing. Not limited to one link.
Linux-based router project supporting a large set of layer-1 technologies (e.g. Ethernet LAN, Wireless LAN, ISDN, DSL, UMTS), layer-3 protocols and functionality (IPv4, IPv6, stateful packet filter), and various network-related functionality (e.g. Bridging, Bonding, VLANs; DNS, DHCPv4, DHCPv6, IPv6 RA; PPP (client+server), PPTP (client+server ...
Some apps default to only download a preview or snippet of your emails until an email is opened. Make sure your app is set to download the full contents of your email for offline use. • Limitations for large folders - Folders containing upwards of 1 million or more emails will have issues downloading all the messages. To resolve this, move ...
Its primary purpose is to provide failover redundancy, especially when used with firewalls and routers. In some configurations, CARP can also provide load balancing functionality. CARP provides functionality similar to Virtual Router Redundancy Protocol (VRRP) and to Cisco Systems' Hot Standby Router Protocol (HSRP).
