New and Updated Features ======================== 2K Mroutes for PIM support – Gryphon, Bingo, Scooter and Skeeter ---------------------------------------------------------------- The scalability number to support PIM Mroutes increased from 1000 Mroutes to 2000 Mroutes in Sparse and Dense mode for Bingo, Gryphon platforms. For Scooter and Skeeter increased from 1000 Mroutes to 2000 Mroutes in Sparse mode only. debug enhancement ----------------- Added debug commands to provide more detail than shown in current counters. New commands are added for LACP packets and spanning tree BPDU packets Default IP address on TOR ------------------------- Added default IP address on interface 1 for inband management. The IP address will appear in configuration as so that users know it is enabled. The IP address is enabled by default and placed in the default VLAN. The default IP address will be overwritten by any DHCP assigned or user configured IP address. DHCP requests should continue to be sent while default IP address is enabled unless DHCP is disabled. Diff flash in iCLI ------------------ Provided a command in ISCLI to display the differences between the running configuration and the saved configuration. This functionality is currently available in IBMNOSCLI and should now be added to the ISCLI. Expand support of ENTITY-MIB ---------------------------- Provided support for the entPhysical, entLogical and entAlias mibs defined in RFC 2737 Entity MIB. Host Resources MIB(RFC-1514) ---------------------------- Provided support for standards based HOST-RESOURCES-MIB defined in RFC 2790 allowing the switches to be managed by standard objectIDs. Host resources mib defines a uniform set of objects to manage host devices that are independent of the vendor, software or network capabilities. Implementation of the system and interface groups is mandatory Next Hop Self ------------- BGP next hop self feature supported with set the IP address for the next hop and override the default behavior used to select next hop LLDP to include vendor, model, OS information --------------------------------------------- Enhanced the customer’s usage of LLDP provide the following changes: enable LLDP by default, add the vendor, model # and operating system in the vendor specific information contained in the LLDP packets. Support added for LLDP device discovery and the switch to report this information in its LLDP packets. LLDP-MIB -------- Supported the requirements in RFC 2863 to define LLDP-MIB for each IBM NOS platform. Support added for each function that is supported by CLI’s LLDP. Feature configuration supported in Blade CLI, ISCLI, BBI and SNMP. OpenFlow Phase 2 ----------------- Added support for Vendor specific MAC masking and multiple-instances to Openflow. MAC masking is used to aggregate unicast FDB entries into a single ACL, ability to forward packets based on masking the first byte, as well as allowing vendor specific options to add/delete/modify entries based on MAC mask values. The multiple instance features provides the ability to support up to four vswitch instances operating as openflow switches. Each instance contains a group of ports that is not shared with any other instances. Precision time Protocol ----------------------- Provided support for hardware assisted PTP synchronization to improve the time accuracy between systems in the network. PTP keeps system time of nodes in a network closely synchronized. Its accuracy is sub-microsecond compared to the millisecond accuracy provided with NTP. The improved accuracy between systems is needed in networks with low latency and increased virtualization networks. MSTP in stacking mode. --------------------- Supported for MSTP mode in stacked environment. The stacked unit will be able to detect and prevent loops within the stack. Also an event that triggers the failover from Master to Backup (or back) will also be supported without causing a loop or breakdown in the network. SNMP and BBI Support for OSPFv3 and MLDv2 ----------------------------------------- IPSec feature was provided in 6.7 release but only in command line interfaces. This release addded configuration and monitoring support for OSPFv3 and MLDv2 via the BBI and SNMP interfaces. Terminal-length 0 persistent ---------------------------- Provided Cisco-like commands for configuring the terminal length for CLI sessions. The commands saved in the flash for persistency across resets. Runtime option to change the terminal length for the current session without affecting the saved configuration. translate VLAN tags on ingress and then mirrors the traffic ----------------------------------------------------------- Created an ACL that can be configured to change the PVID for every packet received. On tagged packets the old VLAN ID will be replaced with the new VLAN ID. On untagged packets the new VLAN ID will be added.The use case is to be able to copy all ingress packets from multiple ports to a single receiver port. The receiver port needs to be able to determine from which port each packet was received. This will be done by assigning a different VLAN ID for each port vLAG scaling ------------ Increased the number of vLAG groups to 50 for Gryphon and Bingo. VMReady MAC Spoofing --------------------- Provided MAC checking mechanism to prevent untrusted devices from spoofing the MAC of a trusted device and gaining access to the VM network. When MAC spoofing is enabled on an ESX server port virtual machines are only allowed to use their assigned MAC address. MAC spoofing can be configured to disable port, drop packets only from intruding MAC, only send a log if MAC checking detects a VM transmitting with a different MAC address than what is listed in VMware’s Vcenter. fcoe stacking on 6.x (Janice only) ---------------------------------- Extended the stacking functionality to include use of fiber channel over Ethernet support. FCoE Stacking ------------- Modified FIPs, DCBX, ETS and PFC modules to support FCoE in stacked topology QBG Stacking ------------ Both stacking and Qbg simplified the network management needs and ease of deployment. Stacking manages multiple switches as a single unit and Qbg provides bridging for the virtualized network. Support for Qbg in a stacked environment further improves the ease of management and deployment of the network even as the network capacity grows QoS Enhancement ---------------- Enhanced QoS priority queue Egress counters to display the following. Number of packets transmitted per queue Rate of packets transmitted per queue Number of packets dropped per queue Rate of packets dropped per queue Store and Forward ------------------ Our switches operate in cut through mode. R7.4 added support for Store and Forward mode with configurable option via CLI. TAGIPVID -------- The feature is to extend the vNICGroup concept at a full DataCenter level Dedicated uplink for vNICGroup mutualized on ToR G8264) and not only at switch edge level (one by one). Gryphon Stacking ---------------- Support for stacking in G8264 for all the features supported in Embedded Switches Stacking.
