ETH Function Setting-Bridge Setting (2 of 2) Aging – enabling aging allows the FBD (Forwarding Data Base) to delete the learnt MAC address if is not communicating for a certain amount of time (FDB Aging Time) On – Aging function is enabled (default setting) Off – Aging function is disabled (MAC address entries will not be deleted from FDB) FDB Aging Time – it is time (in second) for which the FDB will wait before deleting the MAC entry if it is not communicating Default Value = 300 s

Range = 5 to 163680 s

GbE MAX Frame Size – it is the maximum size (in bytes) of the Ethernet frames allowed on Gigabit Ethernet (1 Gbps) ports Default Value = 1522 bytes

Range = 64 to 9600 byes

FE MAX Frame Size – it is the maximum size (in bytes) of the Ethernet frames allowed on Fast Ethernet (100 Mbps) ports Default Value = 1522 bytes

Range = 64 to 2000 byes

VLAN Mode – this option choose the tagging mode in case of VLAN being used 802.1q – VLAN tagging will be done using IEEE 802.1q standard (default setting) 802.1ad – VLAN tagging will be done using IEEE 802.1ad (QinQ, provider bridge) (802.1ad mode is not available for iPasolink EX current version ) Default VLAN ID – it is VLAN ID which will be used as default (native) VLAN Default Value = 1 Range = 1 to 4094 (any VLAN can be set as default VLAN)

Default VLAN

Default VLAN TPID – Tag Protocol Identifier

•For management IP

Default Value = 0x8100 for 802.1Q-tagged frame (Cannot be changed in Rel.2)

•To handle untagged frames •Trunking purpose

ETH Function Setting – ETH Port Setting (2 of 2) Port Usage – Enable or disable the port (by default it is enabled) Port Name – Any user friendly port name can be used (maximum 32 characters) Media Type – Electrical (RJ 45) or Optical (SFP) (by default it is electrical) Speed – Choose among – 100 Mbps, Auto Negotiation (by default it is Auto Negotiation) Electrical Interface

When speed is chosen to be auto negotiated, duplex mode as well as MDI/MDIX will also be auto negotiated Duplex Mode – Full Duplex or Half Duplex (by default it is Full) MDI or MDIX – Medium Dependent Interface or Medium Dependent Interface Crossover (by default it is MDI) MDI ports connect to MDIX ports via straight-through twisted pair cabling; both MDI-to-MDI and MDIX-to-MDIX connections use crossover twisted pair cabling, Auto MDI / MDIX removes these restriction on choosing cable type

Flow Control – Enable or Disable Ethernet Flow Control (by default it is disabled) When sending station transmits data faster than the receiving station can accept it. The overwhelmed network element will send a PAUSE frame, which halts the transmission of the sender for a specified period of time SYNC ETH – Enable or Disable SYNC ETHl (by default it is disabled) Optical SFP

TOPC-E4048E-02

When enabled SYNC ETH clock can be sent from the selected port and the port can be selected as a timing source.

The MSTP maximum hop count value is the maximum number of hops in the region. The MSTI root bridge sends BPDUs with the hop count set to the maximum value. When a bridge receives this BPDU, it decrements the remaining hop count by one and propagates this hop count in the BPDUs it sends. When a bridge receives a BPDU w ith a hop count of zero, the bridge discards the BPDU TOPC-E4048E-02

Steps in quality of service QoS features implementation: – Traffic Conditioning: Traffic conditioning is the process of policing traffic according to the Traffic Conditioning Agreement (TCA). • Classification • Metering • Marking • Policing – Congestion Avoidance: monitor network traffic loads in an effort to anticipate and avoid congestion at common network bottlenecks. Congestion avoidance is achieved through packet dropping by • Weighted Tail Drop (WTD) • Weighted Random Early Detection (WRED) – Congestion Management (Scheduling) : control congestion by determining the order in which packets are sent out an interface based on priorities. the creation of queues, assignment of packets to those queues and scheduling of the packets in a queue for transmission as types of following methods: • Strict Priority (SP) • Deficit Weighted Round Robin (DWRR) • SP+DWRR

QoS/Classification – Port Based QoS Mode Unlike Equipment Based QoS mode, Port Based QoS Mode can assign different Classification Mode for each Port in the IDU. There are three Port Based QoS modes.. Port: This classification mode change the Tagged or Untagged frames CoS to default port priority value. CoS (C-Tag): This classification mode change the untagged frame CoS value to the default port priority value. For tagged frames use the CoS of the incoming frame IPv4.v6 DSCP: This classification mode use the DSCP value in frames with IP header to select the CoS value according to the DSCP Classification Mapping created. For frames without IP Header use the default port priority as the CoS value.

Click on the Port# , to open the Port Classification Mode Setting window for the selected Port. Click the Port Classification Mode drop down list and select: Port , CoS(C-Tag) or IPv4/v6 DSCP . Click the Default Port Priority drop down list and select the default priority level for the port.
