SNMP is used to exchange management information between the network management system (NMS) and a network element (NE).
Chapter 18 SNMP SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations: Table 38 SNMP Commands COMMAND DESCRIPTION Get Allows the manager to retrieve an object variable from the agent. GetNext Allows the manager to retrieve the next object variable from a table or list within an agent.
Chapter 18 SNMP 18.1.3 SNMP v3 and Authentication SNMP v3 adds the use of groups and users to enhance security for SNMP management. Groups are assigned access rights to SNMP objects. Users are members of groups and are therefore limited to the access rights the group has. In addition users can also be required to authenticate before conducting SNMP management sessions.

APPENDIX A Product Specifications This section describes the general software features of the switch. Table 71 Firmware Features FEATURE DESCRIPTION VLAN A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go through a router.
Appendix A Product Specifications Table 71 Firmware Features FEATURE DESCRIPTION Dynamic ARP Dynamic ARP allows you to filter incoming traffic based on the MAC to IP address mapping. The switch can be configured to only allow trusted devices to communicate via its ports. RMON-Lite Remote Network Monitoring Management (RMON) allows you to gather information about the switch’s performance, view statistics and create alarms.

APPENDIX B 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. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.
Appendix B IP Addresses and Subnetting Figure 95 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. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “subnetwork”. A subnet mask has 32 bits.
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 76 Subnet Masks BINARY DECIMAL 1ST OCTET 2ND OCTET 3RD OCTET 4TH OCTET 8-bit mask 11111111 00000000 00000000 00000000 255.0.0.0 16-bit mask 11111111 11111111 00000000 00000000 255.255.0.0 24-bit mask 11111111 11111111 11111111 00000000 255.255.255.
