• Nokia ESB26, 19. DHCP Client MN700004 Rev 01 236 The No IP Error Scenario The above behavior of the DHCP client assumes that it has successfully received an IP address from the DHCP server. If, however, the IP address has not been received, the DHCP client will keep re-sending the request at predefined time intervals until it eventually manages to negotiate an IP address. (For the exact behavior of the DHCP client and managing its retransmission timeout, refer to Changing the DHCPDISCOVER Messages Retransmission Timeout chapter.) NOTES

• Nokia ESB26, MN700004 Rev 01 121 13. Rapid Spanning Tree Protocol (RSTP) Introduction RSTP (Rapid Spanning Tree Protocol) performs the roles of the STP protocol considerably faster by enabling rapid transitions of ports from Alternate state to Root state, and from Backup state to Designated state. In certain cases, RSTP enables rapid transitions of ports to Forwarding states. RSTP is based on IEEE Std 802.1W and is part of Amendment 2: Rapid Reconfiguration to IEEE Std 802.1D and IEEE Std 802.1t-2001. RSTP assigns to each bridge port throughout the Bridged Local Area Network one of the roles summari

• Nokia ESB26, 5. Ethernet Interface Configuration MN700004 Rev 01 35 Setting the Backpressure Mode The backpressure command, in Interface Configuration mode, changes the backpressure mode. Backpressure is a technique for ensuring that a transmitting port does not send too much data to a receiving port at a given time. When the buffer capacity of a receiving port is exceeded, it sends a Jam message to the transmitting port to halt transmission. Backpressure is available only if the port transmits or receives at Half Duplex speed. By default, backpressure is disabled. N

Remote Monitoring MN700004 Rev 01 305 The Ethernet Statistics Group The Ethernet Statistics group contains statistics of packets, bytes, broadcasts, multicasts, and errors, measured by the probe for each monitored Ethernet interface on the switch. Information from the Statistics group is used to detect changes in traffic and error patterns in critical areas of the network. The History Group The History group provides historical views of network performance by taking periodic samples of the counters supplied by the Statistics group. The group is useful for analyzing traffic patterns and trends on an Ethernet interface on the switch and for establishing baseline

Configuring the Watchdog Features Overview The Watchdog is a set of system features for monitoring some tasks or processes on the switch that are either critical or their monitoring is very useful for the administration of the switch. Unlike the other monitoring features however, it also triggers some automated actions to correct the situation if a monitored event or process goes wrong adding thus a bit of artificial intelligence to your switch. The Watchdog is managed in a special Service Configuration mode called "Software Watchdog Configuration mode" (or &qu

• Nokia ESB26, 14. Multiple Spanning Tree Protocol (MSTP) MN700004 Rev 01 143 network. The MST instances combine with the IST at the boundary of the region to become the CST. The IST connects all the MSTP switches in the region and appears as a subtree in the CST that encompasses the entire switched domain, with the root of the subtree being the IST master. The MST region appears as a virtual switch to adjacent STP switches and MST regions. Figure 14-2 shows a network with three MST regions and a legacy 802.1D switch (D). The IST master for region 1 (A) is also the CST root. The IST master for region 2 (B) and the IST master for region 3 (C)
