  DHCP-Snooping Configuration with Aruba Switch Series 2930, 2530. DHCP Snooping  is a Layer 2 security switch feature which blocks unauthorized (rogue) DHCP servers from distributing IP addresses to DHCP clients also call option 82 of this service. This lab configuration with Aruba Switch Series 8320, 2930. We need trusted DHCP server IP address to configure DHCP-snooping on your network.   DHCP Starvation   attack  is a common network attack that targets network  DHCP servers . Its primary objective is to  flood  the organization’s DHCP server with  DHCP REQUEST messages  using  spoofed source MAC addresses . The DHCP server will respond to all requests, not knowing this is a  DHCP Starvation attack , and assign available IP addresses until its  DHCP pool is depleted . At this point the attacker has rendered the organization’s DHCP server useless and can now enable his own  rogue DHCP server  to s...

Peer Keep alive Lab Configuration with Aruba CX Switch Series 8320 This lab configuration with Aruba Switch Series 8320, 2930.   Distribution uses UDP-based peer keep alive message to determine if any link goes down at this level or the peer has completely failed. The following opening rules must be followed to use peer keep alive links. 1.       An IP address must be configure for a peer keep alive VLAN interface and the same IP address must be configured as a peer keep alive distribution on the peer distribution switch.   2.       There must be logical layer 3 connectivity between the two IP address configured for the peer keep alive VLAN interface.   3.       STP cannot run on a peer-keep alive links.   4.       A keep alive VLAN can only have one member port.   5.       The default VLAN can’t configure for a peer ke...
