    When multiple hardware queues represent a single logical service queue, the system automatically monitors the offered load and forwarding rate of each hardware queue. Based on the monitored state of each hardware queue, the system imposes an individual CIR and PIR rate for each queue 7750 SR OS Services Guide Page 33...

    Each hardware queue representing a service queue is mapped to a special destination in the traffic manager that ‘forwards’ the packet back to the ingress forwarding plane allowing a second pass through the traffic manager. In the second pass, the packet is placed into a ‘shared’ Page 34 7750 SR OS Services Guide...

    VLAN-id is port specific, those connected to different ports might have the same VLAN. The aggregation side (the right side Figure 47) is aggregated on the same port, and hence, unique a VLAN-id is required. 7750 SR OS Services Guide Page 221...

    When deployed with multi-chassis LAG, the path for return traffic is maintained through the pseudowire or VPLS switchover, which enables carriers to deliver “always on” services across their IP/MPLS networks. Page 222 7750 SR OS Services Guide...

    The behavior of the pseudowire redundancy feature is the same if PE1 detects or is notified of a network failure that brought the spoke SDP operational status to DOWN. The following are the events which will cause PE1 to trigger a switchover to the secondary standby pseudowire: 7750 SR OS Services Guide Page 223...

    VLL Service Considerations This section describes various of the general 7750 SR service features and any special capabilities or considerations as they relate to VLL services. SDPs The most basic SDPs must have the following: • A locally unique SDP identification (ID) number.

  • Page 235: Sdp Statistics For Vpls And Vll Services

    With this feature the operator will have local CLI based as well as SNMP based statistics collection for each VC used in the SDPs. This will allow for traffic management of tunnel usage by the different services and with aggregation the total tunnel usage. 7750 SR OS Services Guide Page 235...

    The endpoints of Frame Relay VLLs must be Data-Link Connection Identifiers (DLCIs) on any port that supports Frame Relay. The pseudowire encapsulation, or SDP vc-type, supported is the 1- to-1 Frame Relay encapsulation mode. Page 236 7750 SR OS Services Guide...

  • Page 237: Pwe3 N-To-1 Cell Mode

    In SDU mode, the mandatory PWE3 control word is supported. This allows the ATM VLL to transport OAM cells along with SDU frames, using the “T” bit to distinguish between them, to recover the original SDU length, and to carry CLP, EFCI and UU information. 7750 SR OS Services Guide Page 237...

    Apipes cannot perform any classification and on Fpipes Layer 3 (IP) classification is performed. Filter Policies 7750 SR Epipe, Fpipe, and Ipipe services can have a single filter policy associated on both ingress and egress. Both MAC and IP filter policies can be used on Epipe services.

RADIUS Accounting In the 7750 SR OS, the accounting paradigm is based on sla-profile instances, yet this is at odds with traditional RADIUS authentication and accounting which is host-centric. In previous OS releases, it was possible to have many hosts sharing a common sla-profile instance, and thus accounting and QoS parameters.

  • Page 864: Routing Protocols

    Either ICMP ping or unicast ARP mechanism can be used to test the connectivity. ICMP ping is preferred. If the connectivity check fails and the static route is de-activated, the router will continue to send polls and re-activate any routes that are restored. Page 864 7750 SR OS Services Guide...

  • Page 865: Qos Policies

    Internet Enhanced Services QoS Policies When applied to 7750 SR IES services, service ingress QoS policies only create the unicast queues defined in the policy. The multipoint queues are not created on the service. With IES services, service egress QoS policies function as with other services where the class-based queues are created as defined in the policy.
