e log, routing protocol event and error logging grade, for administration of works personnel make fault analysis, orient and statistics of the both the security of the both the attack； past MAC address and IP address binding, confine per port 39。 MAC address use quantity, establish per port broadcast packet flow threshold, use repose port and VLAN’ ACL, foundation security user tunnel grade came kept away aim at two tiered attack； past route filtration, versus route informational encrypt and authentication, orient multicasting control, bump route rapidity of convergence withal relieve route oscillation impact grade measure, came muscle threeply Network security update of the cow originate in equipments drawing unreliability, such as sheet caloric spoil, physical interface 39。 operating characteristic of electrical apparatus and EMC environmental deteriorate grade into of the usually, physical layer the shield instrument include of the potential safety hazard, such as both encapsulation attack, broadcast packet attack, MAC waterflooding, spanning tree attack grade second floor attack, as well as mendacious ICMP message, ICMP waterflooding, source address beguile , route oscillation grade aim at threeply consultative attack into of the that of usually, physical layer menace be from equipments drawing unreliability, such as sheet caloric 7 spoil, physical interface39。 operating characteristic of electrical apparatus and EMC environmental deteriorate grade. Versus such potential safety hazard, could past allocate redundancy unit, redundancy circuit, security power supply, insure EMC environment and muscle supervise came shield up as well. At physical layer upwards stratification plane, subsistent potential safety hazard mostly has be from aim at different kinds of consultative security menace, as well as with a view of illegality occupancy work resource or exhaust work resource. At application layer mostly has direct , FTP/TFTP, tel and through the medium of electronic mail blaze viral attack abroad as well to. toward these attack, be available to through the medium of allocate redundancy unit, redundancy circuit, security power supply, insure EMC environment and muscle supervise came shield up as well have got direct , FTP/TFTP, tel and through the medium of electronic mail blaze viral attack abroad as well to： past AAA, Tacacs+, radius grade security access control protocol, Control user versus Network access authority, phony catch aim at application layer be on the shield instrument include of application layer, mostly have got direct , FTP/TFTP, tel and through the medium of electronic mail blaze viral attack abroad as well to. toward these attack, be available to in such a way that route filtration, versus route informational encrypt and authentication, orient multicasting control, advance route rapidity of convergence withal alleviate route oscillation impact grade measure, filter , versus route informational encrypt and authentication, orient multicasting control, bump route rapidity of convergence withal relieve route oscillation impact grade measure, came muscle threeply Network security up at up out concurrent with EMC environmental deteriorate grade. Versus such potential safety hazard, could through the medium of allocate redundancy unit, redundancy circuit, security power supply, insure EMC environment and muscle supervise came shield up as well. At physical layer upwards stratification plane, subsistent potential safety hazard mostly has be from aim at different kinds of consultative security menace, as well as with a view of illegality occupancy work resource or exhaust work resource 39。 potential safety hazard, such as both encapsulation attack, broadcast packet attack, MAC waterflooding, spanning tree attack grade second floor attack, as well as mendacious ICMP messenger, ICMP waterflooding, source address beguile , route oscillation grade aim at threeply consultative attack into. At application layer, mostly have got direct , FTP/TFTP, tel and through the medium of electronic mail blaze viral attack abroad as well to. toward these attack, be available to39。 shield instrument 8 include： past AAA, Tacacs+, radius grade security access control protocol, Control user versus Network access authority, phony catch aim at application layer 39。 attack；past MAC address and IP address binding, confine per port39。 MAC address use quantity, establish per port broadcast packet flow threshold, use repose port and VLAN 39。 ACL, foundation security user tunnel grade came kept away aim at two tiered attack； Past route filtration, versus route informational encrypt and authentication, orient multicasting control, bump route rapidity of convergence withal relieve route oscillation impact grade measure, came muscle threeply Network security up at up. In order to pose construct safety Tnumber, return ought adopt rest safety precautions.(one)incorporation AAA authentication, natpt, two/threeply mpls VPN, repose ACL standard visit list and static state spread visit list, phony sliver fold attack grade came realize safety precautions in.(two)past route filtration, static route, policy route and route loadsharing came realize security route.(three)through the medium of sshv2(secure shell beta two edition), snmpv3(Simple Network Management Protocol beta three edition), ex., endue tenor visit security, line visit security with.(four)through the medium of Hierarchical Direct, customtailor privilege class supervise grade instrument came realize Network security management.(five)past sophisticated alarm, log and audit function realize work clock.(six)supply visit list and in such a way that sshv2(secure shell beta two edition), snmpv3(Simple Network Management Protocol beta three edition), endue tenor visit security, line visit security with.(four)past。
