CHAPTER 18 SNMP This chapter describes how to user Simple Network Management Protocol (SNMP) to manage and monitor the Switch. 18.1 About SNMP Simple Network Management Protocol (SNMP) is an application layer protocol used to manage and monitor TCP/IP-based devices. 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 In addition, SNMP managers can also be required to authenticate with agents before conducting SNMP management sessions. " SNMP v3 is enabled when you create SNMP groups and users. Once SNMP v3 is enabled, you must configure unique SNMP communities for SNMP v1 and/or SNMP v2c access. 18.1.4 SNMP EngineID The SNMP Engine ID is a unique identifier that identifies agents to the managers. The default SNMP Engine ID is the MAC address of the agent. You can change this.

P ART IV Appendices and Index IP Addresses and Subnetting (151) Legal Information (157) Customer Support (161) Index (167) 147
APPENDIX A 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 A IP Addresses and Subnetting Figure 89 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 A 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 74 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.

Appendix A IP Addresses and Subnetting Figure 91 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address). 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address.
