Command parameters and uses are listed for the following utilities in Tables 1 through 9: ■ Arp ■ Ipconfig ■ Netsh ■ Netstat ■ Pathping ■ Ping ■ Route ■ Tracert ARP The Arp utility reads and manipulates local ARP tables (data link address-to-IP address tables). Syntax arp -s inet_addr eth_addr [if_addr] arp -d inet_addr [if_addr] arp -a [inet_address] [-N if_addr] [-v] Table 1 ARP command parameters and uses Parameter Description -a or -g Displays current entries in the ARP cache. If inet_addr is specified, the IP and data link address of the specified computer appear. If more than one network interface uses ARP, entries for each ARP table appear. inet_addr Specifies an Internet address. -N if_addr Displays the ARP entries for the network interface specified by if_addr. -v Displays the ARP entries in verbose mode. -d Deletes the host specified by inet_addr. -s Adds the host and associates the Internet address inet_addr with the data link address eth_addr. The physical address is given as six hexadecimal bytes separated by hyphens. The entry is permanent. eth_addr Specifies physical address. if_addr If present, this specifies the Internet address of the interface whose address translation table should be modified. If not present, the first applicable interface will be used.

  • Timeout Control in Distributed Systems Using Perturbation Analysis
    2011 50th IEEE Conference on Decision and Control and European Control Conference (CDC-ECC) Orlando, FL, USA, December 12-15, 2011 Timeout Control in Distributed Systems Using Perturbation Analysis Ali Kebarighotbi and Christos G. Cassandras Division of Systems Engineering and Center for Information and Systems Engineering Boston University Brookline, MA 02446 [email protected],[email protected] Abstract— Timeout control is a simple mechanism used when direct feedback is either impossible, unreliable, or too costly, as is often the case in distributed systems. Its effectiveness is determined by a timeout threshold parameter and our goal is to quantify the effect of this parameter on the behavior of such systems. In this paper, we consider a basic communi- cation system with timeout control, model it as a stochastic flow system, and use Infinitesimal Perturbation Analysis to Fig. 1. Timeout controlled distributed system determine the sensitivity of a “goodput” performance metric with respect to the timeout threshold parameter. In conjunction with a gradient-based scheme, we show that we can determine an optimal value of this parameter. Some numerical examples with an action Ai, a proper response to a timeout event is are included. normally related to the state and action at time t − θi.A simple example is repeating Ai at t because no desirable NTRODUCTION I. I response has been observed in [t − θi; t). Thus, a controller Timeout control is a simple mechanism used in many must have some information about both current and past systems where direct feedback is either impossible, unreli- states and actions of the system.

  • June 2021 Uptime Policy
    June 2021 Uptime Policy The xx network is targeting 80% Uptime, 94% Round Success Rate and .5% Realtime Timeout requirements for June 2021. This means that generally, a node needs to be online for at least 80% of the month of May 2021, successfully complete at least 94% of the rounds the node participates in and not fail more than .5% of the Realtime phase of a round to receive compensation for the month. A node will be considered online as long as it is pinging the permissioning server regularly. If at the dashboard, your node is listed as either “Online” or “Error”, it is still online for the purpose of compensation for the month of June 2021. On the individual node pages on the dashboard there are monthly and weekly uptime metrics to inform you of your progress. Node uptime is not tracked while xx network’s servers are down and such periods will not be counted against the minimum. In the event the network is down due to a software update or a bug caused by the xx network team, those periods will also not count towards the 80% uptime minimum. Grace Period Nodes who are joining the network for the first time this month (Orange Team X) will have the entire month of June 2021 as a grace period. This only includes nodes who registered initially to start in June 2021. If this month is a grace period for your node, you will receive an email notifying you. The grace period in June 2021 is designed to allow new nodes adequate time to onboard.

  • WLAN Timeouts
    WLAN Timeouts • Timeout for Disabled Clients, on page 1 • Session Timeouts, on page 1 • User Idle Timeout per WLAN, on page 3 • Address Resolution Protocol Timeout, on page 4 • Authentication of Sleeping Clients, on page 4 Timeout for Disabled Clients You can configure a timeout for disabled clients. Clients who fail to authenticate three times when attempting to associate are automatically disabled from further association attempts. After the timeout period expires, the client is allowed to retry authentication until it associates or fails authentication and is excluded again. Use these commands to configure a timeout for disabled clients. Configuring Timeout for Disabled Clients (CLI) • Configure the timeout for disabled clients by entering the config wlan exclusionlist wlan_id timeout command. The valid timeout range is 1 to 2147483647 seconds. A value of 0 permanently disables the client. • Verify the current timeout by entering the show wlan command. Session Timeouts You can configure a WLAN with a session timeout. The session timeout is the maximum time for a client session to remain active before requiring reauthorization. If a WLAN is configured with Layer 2 security, for example WPA2-PSK, and a Layer 3 authentication is also configured, the WLAN session timeout value is overridden with the dot1x reauthentication timeout value. If apf reauthentication timeout value is greater than 65535, the WLAN session timeout is by default set to 65535; else, the configured dot1x reauthentication timeout value is applied as the WLAN session timeout. This section contains the following subsections: WLAN Timeouts 1 WLAN Timeouts Configuring a Session Timeout (GUI) Configuring a Session Timeout (GUI) Configurable session timeout range is: • 300-86400 for 802.1X(EAP) • 0-65535 for all other security types Note If you configure a session-timeout of 0, it means 86400 seconds for 802.1X (EAP), and it disables the session-timeout for all other security types.
