PowerConnect M6220/M6348/8024/8024F/M8024/M8024-k/ 7024/7048/7024P/7048P/7024F/7048R/7048R-RA Release Notes  Link Local Protocol Filtering Link Local Protocol Filtering blocks Cisco link local protocols from being flooded in the network. By default, PowerConnect switches process and respond to Cisco CDP packets. However, in networks where this capability is not desirable or other Cisco proprietary packets are flooded over the network, the administrator can disable flooding of Cisco link local protocols. The following table identifies the matching criteria for filtering Cisco proprietary packets: Rule Type Blockcdp Blockvtp Blockdtp Blockudld Blockpagp Blocksstp Blockall Rule Purpose Used to block CDP PDU's Used to block VTP PDU;s Used to block DTP PDU's Used to block UDLD PDU's Used to block PAGP PDU's Used to block SSTP PDU's Used to block all defined Protocol Filtering PDU's Blocked Destination MAC Address N/A N/A N/A N/A N/A N/A 01:00.0C:CC:CC:C0 Ether Type 0x2000 0x2003 0x2004 0x0111 0x0104 0x010b N/A  DHCP Server The PowerConnect Series switches support a simple DHCP server capability for domains that do not wish to deploy a redundant DHCP address assignment solution or who have need of a temporary solution while (re)deploying their DHCP server solution. In configuring DHCP scopes, be aware that the DHCP pool address and netmask must exactly match a VLAN address and netmask assignment for DHCP addresses to be served over that VLAN. Only a single manual IP address can be assigned to a pool. The address must have a netmask of 32.  GMRP The GARP Multicast Registration Protocol provides a mechanism that allows networking devices to dynamically register (and de-register) Group membership information with the MAC networking devices attached to the same segment, and for that information to be disseminated across all networking devices in the bridged LAN that support Extended Filtering Services. The PowerConnect Series switches support GMRP as specified in IEEE 802.1Q 1998.  WRED Weighted random early drop is supported on certain PowerConnect series switches. Refer to the table at the beginning of this section for further information. CoS queue configuration involves the following hardware port queue configuration parameters:  scheduler type: strict vs. weighted  minimum guaranteed bandwidth  maximum allowed bandwidth (i.e. shaping)  queue management type: tail drop vs. WRED  tail drop parameters: threshold  WRED parameters: minimum threshold, maximum threshold, drop probability System Firmware Version 4.1.0.6 Page 5
