Cisco 3560 switch interface traffic grabbing vbs scriptTo make it easy for you to view the traffic of the vswitch interface, the customer does not log on to the vswitch, and does not have any network management traffic statistics device. Simply write a vbs script, which is simple and usable. On error resume next dim wshellset WshShell = WScript. createObject ("WScript. shell ") WshShell. run "cmd" WshShell

Disable forwarding of a specific MAC address on a cisco SwitchIt is really annoying to see other illegal DHCP in the LAN. In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of machine A is 00-01-02-03-04-05, which is connected to port F0/3 of Switch B, port F0/3 is in VLAN3. Currently, forwarding of A is blocked on port B. You can set the following accord

Cisco switch port broadcast storm settings are more practical. When a port receives a large number of broadcast, unicast, Or multicast packets, a broadcast storm occurs. Forwarding these packets will slow down the network or cause timeout. Using broadcast storm control on ports can effectively avoid network paralysis caused by hardware damage or link failure. By default, broadcast, multicast, and unicast st

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging

In the network World, Cisco System Inc. Nobody knows, no one does not know. With its IOS (Internet operating System), Cisco is an absolute leader in the multiprotocol router market. Currently, nearly 80% of the routers in the Internet are from Cisco. In fact, in addition to the main product of the router, Cisco also ha

There are still many things worth learning about Cisco switches. Here we mainly introduce the Cisco switch interface mode. In a Cisco switch network, there are four main types of interfaces in the LAN that are ultimately stable: access/trunk/multi/dot1q-tunnel. 1. access: it

The naming rules for Cisco switches are more complex than the naming rules for routing,Look at these:ws-c2960-24tc-l, WS-C2950G-24-EI-DC, Ws-c2960-24tt-l, Ws-c3750g-24ts-e, Ws-c3750g-24t-s, We didn't find them on the switch, we just saw the Catalyst 2950 series and wrote it all: The Cisco Catalyst 2950 Series, which means the
