Switch to prevent DHCP access

Switch to prevent DHCP access

So you just have to block port UDP 67 (DHCP DISCOVER) or UDP 68 (DHCP OFFER) (depend if you want to block input or output, or maybe both) except on the desired switch port. Many manufactures of switches offer options on their managed equipment to handle this. DHCP snooping acts like a firewall between untrusted hosts and trusted DHCP servers. I have two DHCP server and now needs to block a particualr DHCP from entering the switch How to do it via an ACL and bind this to a port ? thank you for suggestion Do you have a dhcp serve on a specific port and want to block it from responding to dhcp requests? Can you not disable it? The DHCP. Is it possible in a managed switch such as a 3com 4500 or a HP Baseline PWR-Plus type switch to block DHCP from being served through specific ports, or all except 1 port? I have a DHCP server for example plugged in to port 1, I need that to continue working, but I want to prevent the issue where a. It filters untrusted DHCP messages and builds a binding database (DHCP snooping binding table) that maps client MAC addresses, IP addresses.

Does the access switch need to have multicast enabled

Does the access switch need to have multicast enabled

yes you need multicast routing enabled and ip pim sparse-dense mode under both SVI interfaces. You can check the status of igmp snooping on catalyst 1300 access layer switches. To support selective IPv4 Multicast forwarding, bridge Multicast filtering must be enabled (in Multicast. IP multicast is a method of transporting Internet Protocol (IP) datagrams from a single source [device or application transmitting the multicast] to a group of interested receivers [devices or applications on devices that are interested in receiving the data] in a single transmission. In the factory default state (IGMP disabled), the switch simply floods all IP multicast traffic it. This is accomplished by allowing network devices, primarily routers and switches, to replicate the data stream only when necessary, directing it along.

Check the duplex mode of the access switch

Check the duplex mode of the access switch

The switches that run Cisco IOS Software default to auto-negotiation for speed and are set to on for the duplex. The switches can also set their duplex setting with the duplex interface subcommand, and their speed with—you guessed it—the speed interface subcommand. This is only applicable for 10/100/1000 Mbps (1000BASE-T) NICs only Assuming maximum capability of Catalyst switch, and NIC is 1000 Mbps, full-duplex. I would like to know what duplex (half or full) my network card has negotiated with a switch when they are both set to auto configuration in Windows.
