Chapter 10 Troubleshooting Check if the auto-discovery program is still active (you can see a Stop button in the Auto- Discovery screen if it is; otherwise, a Discover button displays instead). Wait for a while and check the OTV again if the program is running. Make sure your auto-discovery filter rule(s) do not exclude the device.

Chapter 10 Troubleshooting 10.9 Syslog Problems I cannot see any device logs in the Tool > Syslog View > Log Viewer screen. The ENC does not automatically collect system logs from devices. To see a device’s syslog on the ENC, you have to configure the syslog settings on devices to forward syslogs to the ENC server. If the syslog settings on the device is properly configured but you still cannot see any of them on the ENC, make sure no firewall or any devices between the device and the ENC blocks the traffic.

Page 267: Appendix B Ip Addresses And Subnetting
PP EN D I X IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
Page 268 Appendix B IP Addresses and Subnetting The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID. Figure 206 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask.
Page 269 Appendix B IP Addresses and Subnetting Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Table 136 Subnet Masks BINARY DECIMAL 4TH OCTET OCTET...

In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.
Page 271 Appendix B IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two sub- networks, A and B. Figure 208 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 2 –...

If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.
Page 275 Appendix B IP Addresses and Subnetting IP Address Conflicts Each device on a network must have a unique IP address. Devices with duplicate IP addresses on the same network will not be able to access the Internet or other resources. The devices may also be unreachable through the network.
Page 276 Appendix B IP Addresses and Subnetting Conflicting Computer and Router IP Addresses Example More than one device can not use the same IP address. In the following example, the computer and the router’s LAN port both use 192.168.1.1 as the IP address. The computer cannot access the Internet.
