Switch(config)# interface ethernet 2/1 Configures the interface type and location. Step 3 switch(config-if)# shutdown Example: switch(config-if)# shutdown Shuts down or disconnects the affected ports. After disconnecting the affected ports, locate every switch in the redundant paths using your network topology diagram. Step 4 switch(config-if)# show spanning-tree vlan vlan-id Example: switch(config-if)# show spanning-tree vlan 9VLAN0009 Spanning tree enabled protocol rstp Root ID Priority 32777'' Address 0018.bad7.db15'' Cost 4... Verifies that the switch lists the same STP root bridge as the other nonaffected switches. Step 5 (Optional) switch(config-if)# show spanning-tree interface interface-type slot/port detail Example: switch(config-if)# show spanning-tree interface ethernet 3/1 detail Port 385 (Ethernet3/1) of VLAN0001 is root forwarding Port path cost 4, Port priority 128, Port Identifier 128.385 Designated root has priority 32769, address 0018.bad7.db15 Designated bridge has priority 32769, address 0018.bad7.db15 Designated port id is 128.385, designated path cost 0 Timers: message age 16, forward delay 0, hold 0 Number of transitions to forwarding state: 1 The port type is network by default Link type is point-to-point by default BPDU: sent 1265, received 1269 (Optional) Verifies that the root port and alternate ports are regularly receiving BPDUs. Step 6 (Optional) switch(config-if)# show interface counters errors Example: switch(config-if)# show interface counters errors --------------------------------------------------------------Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards--------------------------------------------------------------mgmt0 -- -- -- -- -- --Eth1/1 0 0 0 0 0 0Eth1/2 0 0 0 0 0 0Eth1/3 0 0 0 0 0 0Eth1/4 0 0 0 0 0 0Eth1/5 0 0 0 0 0 0Eth1/6 0 0 0 0 0 0Eth1/7 0 0 0 0 0 0Eth1/8 0 0 0 0 0 0 (Optional) Checks the hardware packet statistic (error drop) counters. Example This example shows that the designated port is regularly sending BPDUs: switch# show spanning-tree interface ethernet 3/1 detail Port 385 (Ethernet3/1) of VLAN0001 is root forwarding Port path cost 4, Port priority 128, Port Identifier 128.385 Designated root has priority 32769, address 0018.bad7.db15 Designated bridge has priority 32769, address 0018.bad7.db15 Designated port id is 128.385, designated path cost 0 Timers: message age 16, forward delay 0, hold 0 Number of transitions to forwarding state: 1 The port type is network by default Link type is point-to-point by default BPDU: sent 1265, received 1269 This example shows how to check the hardware packet statistic counters for a possible BPDU error drop: switch# show interface counters errors --------------------------------------------------------------Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards--------------------------------------------------------------mgmt0 -- -- -- -- -- --Eth1/1 0 0 0 0 0 0Eth1/2 0 0 0 0 0 0Eth1/3 0 0 0 0 0 0Eth1/4 0 0 0 0 0 0Eth1/5 0 0 0 0 0 0Eth1/6 0 0 0 0 0 0Eth1/7 0 0 0 0 0 0Eth1/8 0 0 0 0 0 0 Troubleshooting Excessive Packet Flooding Unstable STP topology changes can trigger excessive packet flooding in your STP network. With Rapid STP or Multiple STP (MST), a change of the port's state to forwarding, as well as the role change from designated to root, can trigger a topology change.

DecodePeerAddress transforms the binary-encoded host:port address into ahuman-readable format. So, "abcdef" becomes 97.98.99.100:25958. func RegisterFlags(c *Config) Registers Config fields as command line flags. If c is nil, DefaultConfigis used. Config for the DHT Node. Use NewConfig to create a configuration with default values.

It provides DHT features to a torrentclient, such as finding new peers for torrent downloads without requiring atracker.ExampleDHT is a simple example that searches for a particular infohash andexits when it finds any peers.

Inside the request callback you can manipulate the message the way you want.server.js { console.log('Server message:', message); message.transmitTimestamp = Math.floor(Date.now() / 1000); response(message);});// Check if node has the necessary permissions// to listen on ports less than 1024// err => { if (err) throw err; console.log('Server listening');});">const NTPServer = require('ntp-time').Server;const server = new NTPServer();// Define your custom handler for requestsserver.handle((message, response) => { console.log('Server message:', message); message.transmitTimestamp = Math.floor(Date.now() / 1000); response(message);});// Check if node has the necessary permissions// to listen on ports less than 1024// err => { if (err) throw err; console.log('Server listening');});For more didatic code, go to the examples page..

Switch(config)# interface ethernet 2/1 Configures the interface type and location. Step 3 switch(config-if)# shutdown Example: switch(config-if)# shutdown Shuts down or disconnects the affected ports. After disconnecting the affected ports, locate every switch in the redundant paths using your network topology diagram. Step 4 switch(config-if)# show spanning-tree vlan vlan-id Example: switch(config-if)# show spanning-tree vlan 9VLAN0009 Spanning tree enabled protocol rstp Root ID Priority 32777'' Address 0018.bad7.db15'' Cost 4... Verifies that the switch lists the same STP root bridge as the other nonaffected switches. Step 5 (Optional) switch(config-if)# show spanning-tree interface interface-type slot/port detail Example: switch(config-if)# show spanning-tree interface ethernet 3/1 detail Port 385 (Ethernet3/1) of VLAN0001 is root forwarding Port path cost 4, Port priority 128, Port Identifier 128.385 Designated root has priority 32769, address 0018.bad7.db15 Designated bridge has priority 32769, address 0018.bad7.db15 Designated port id is 128.385, designated path cost 0 Timers: message age 16, forward delay 0, hold 0 Number of transitions to forwarding state: 1 The port type is network by default Link type is point-to-point by default BPDU: sent 1265, received 1269 (Optional) Verifies that the root port and alternate ports are regularly receiving BPDUs. Step 6 (Optional) switch(config-if)# show interface counters errors Example: switch(config-if)# show interface counters errors --------------------------------------------------------------Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards--------------------------------------------------------------mgmt0 -- -- -- -- -- --Eth1/1 0 0 0 0 0 0Eth1/2 0 0 0 0 0 0Eth1/3 0 0 0 0 0 0Eth1/4 0 0 0 0 0 0Eth1/5 0 0 0 0 0 0Eth1/6 0 0 0 0 0 0Eth1/7 0 0 0 0 0 0Eth1/8 0 0 0 0 0 0 (Optional) Checks the hardware packet statistic (error drop) counters. Example This example shows that the designated port is regularly sending BPDUs: switch# show spanning-tree interface ethernet 3/1 detail Port 385 (Ethernet3/1) of VLAN0001 is root forwarding Port path cost 4, Port priority 128, Port Identifier 128.385 Designated root has priority 32769, address 0018.bad7.db15 Designated bridge has priority 32769, address 0018.bad7.db15 Designated port id is 128.385, designated path cost 0 Timers: message age 16, forward delay 0, hold 0 Number of transitions to forwarding state: 1 The port type is network by default Link type is point-to-point by default BPDU: sent 1265, received 1269 This example shows how to check the hardware packet statistic counters for a possible BPDU error drop: switch# show interface counters errors --------------------------------------------------------------Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize OutDiscards--------------------------------------------------------------mgmt0 -- -- -- -- -- --Eth1/1 0 0 0 0 0 0Eth1/2 0 0 0 0 0 0Eth1/3 0 0 0 0 0 0Eth1/4 0 0 0 0 0 0Eth1/5 0 0 0 0 0 0Eth1/6 0 0 0 0 0 0Eth1/7 0 0 0 0 0 0Eth1/8 0 0 0 0 0 0 Troubleshooting Excessive Packet Flooding Unstable STP topology changes can trigger excessive packet flooding in your STP network. With Rapid STP or Multiple STP (MST), a change of the port's state to forwarding, as well as the role change from designated to root, can trigger a topology change. Rapid STP immediately flushes
