29 Enhancements Release M.08.89 Enhancements IP address of 10.10.100.27 is assigned a host name of accounts015 and another IP address of 10.10.100.33 is assigned a host name of sales021 , then the switch configured wit h the domain suffix evergreen.trees.
30 Enhancements Release M.08.89 Enhancements ■ The host’ s domain must be reachable f rom the swit ch. This requires that the DNS server for the switch must be able to co mmunicate with the DNS server(s) in the path to the domain in which the targ et host operat es.
31 Enhancements Release M.08.89 Enhancements Configuring a DNS Entry The switch allows one DN S server entry , which in cludes the DNS server IP address and the chosen domain name suffix. Config urin g the entry enables the use of ping and tracerou te with a target’ s host name instead of the target’ s IP address.
32 Enhancements Release M.08.89 Enhancements Figure 5. Example Netw ork Domain Configuring switch “A” with the dom ain name and the IP address of a DNS server for th e domain enables the switch to use host names assigned to IP addresses in th e domain to perform ping and traceroute actions on the devices in the domain.

35 Enhancements Release M.08.89 Enhancements Event Log Messages Using SNMP T o View and Configure Switch Authentication Features In earlier software releases, SNMP MIB object a ccess has not been available for switch au thenti cation configuration (hpS witchAuth) features.
36 Enhancements Release M.08.89 Enhancements Security Notes Passwords and keys confi gured in the hp Switch Auth MI B are not returned via SNMP , and th e response to SNMP queries for such information is a null string. Ho wever , SNMP sets can be used to configure passwo rd an d key MIB objects.
37 Enhancements Release M.08.89 Enhancements For example, to disable SNMP access to the switch’ s authentication MIB and then display the result in the Excluded MIB field, you woul d execu te the fo ll owing two comm ands.
38 Enhancements Releases M.08.90 and M.08.91 Enhancements Figure 11. Using the show ru n Command to View the Current Authenticatio n MIB Access State Releases M.08.90 and M.08.91 Enhancements ■ The MSTP enhancement implementing the CLI command for sp anning-tree legacy-path-cost was included in releaseM.
39 Enhancements Releases M.08.90 and M.08.91 Enhancements The “legacy-path-cost” CLI comman d does not affe ct or replace functionality of the “spanning- tree force-version” command. The “spanning-tr ee force-version” controls whether MSTP will send and process 802.
40 Enhancements Releases M.08.90 and M.08.91 Enhancements Note Changing the QoS Pass-Thr ough Mode can be done without rebootin g the switch. Howe ver , the switch ports are toggled down and back up, allowing the Qo S queues to be reconfig ured. This may affect routing and sp anning tree operation.
41 Enhancements Releases M.08.90 and M.08.91 Enhancements QoS Pass-Through Mode SNMP MIB Object. A read-write MIB object, 1.3.6.1.4.1.11.2.14.11.5.1. 7.1.24.1, has been added to the ProCurve switch MI B. The QoS Pass-Through Mode can be changed using either an SNMP network management appl ication or the CLI setmib command.
42 Enhancements Release M.08.94 Enhancements The current QoS Pass-Thro ugh Mode also is displ ayed in the show running -config command output. Operating Notes ■ T o use the same QoS queue structure used in pre-M.08.78 software , se t the QoS Pass-Through Mode to balanced .
43 Enhancements Release M.08.94 Enhancements Example In the routin g switch shown belo w , option 82 has been configu red with mgmt-vlan for t he Remote ID. ProCurve(config)# dhcp-relay option 82 append mgmt-vlan The resulting effect on DHCP operation for clients X, Y , and Z is shown in Ta b l e 3 .
44 Enhancements Release M.08.94 Enhancements T able 3. DHCP Operation for th e T opology in Figure 12 Operating Notes ■ Routing is not allowed between the Manage ment VLAN and other V LANs. Thus, a DHCP server must be available in the Management VL AN if there are clie nts in the Manageme nt VLAN that require a DHCP server .
45 Enhancements Releases M.08.95 th rough M.10.01 Enhancements Releases M.08.95 throug h M.10.01 Enhancements Software fixes only; no new enhancements. Release M.08.96 Enhancements ■ Enabled use of login "Messa ge of the Day" (MOT D) banner .
46 Enhancements Release M.10.02 Enhancements ■ An ACL must be configured on the RADIUS ser ver (instead of the sw itch) by creating and assigning one or more Access Control Entrie s to the username/password pair or MAC address of the client f or which you want ACL support.
47 Enhancements Release M.10.02 Enhancements T able 4. Contrasting Dynamic a nd Static ACLs RADIUS-Based (Dynamic) ACLs Port-Based (Static) ACLs Operates on the 3400cl switches. Operates on both the 3400cl and 6400c l switches. Configured in client a ccounts on a RADIUS server .
48 Enhancements Release M.10.02 Enhancements T erminology ACE: See Access Control Entry , b elow . Access Control Entry (ACE): An ACE is a policy consisting of a packet-handling actio n and criteria to define the packets on which to apply th e action.
49 Enhancements Release M.10.02 Enhancements packet (from the authenticated c lient) that is no t explicitly permit ted or denied by ot her ACEs configured seq uentially earlier in the ACL. Unless otherwise no ted, “implicit deny IP any” refers to the “deny” act ion enforced by both standard and ex tended ACLs.
50 Enhancements Release M.10.02 Enhancements the client MAC ad dress is the select ion criteria, o n ly the client having that MAC address can use the correspondin g ACL. Wh en a RADIU S server authen ticates a client, it also assig ns the ACL configured with that client’ s cr edentials to the port.
51 Enhancements Release M.10.02 Enhancements Example. Suppose the ACL in Figure 3 is assigned to filt er the traffic from an authenticated client on a given port in the switch: Figure 3. Example of Seque ntial Comparison As shown above, the ACL tries to apply the first ACE in the list.
52 Enhancements Release M.10.02 Enhancements Figure 4. The Packet-Filteri ng Process in an ACL with N Entr ies (ACEs) Note The order in which an ACE oc curs in an ACL is significant.
53 Enhancements Release M.10.02 Enhancements For example, suppose you want to configure a RAD IUS-based ACL to invoke these policies in the 11.11.11.0 network: 1. Permit inbound client traf fic with a DA of 11.11.11.42. 2. Permit inbound T elnet traffic for DA 11.
54 Enhancements Release M.10.02 Enhancements General Steps These steps suggest a process for using ACLs to estab lish client access policies. The topi cs following this section provide details. 1. Determine the polices you want to e nforce for client traffic inbound o n the switch.
55 Enhancements Release M.10.02 Enhancements ■ Is it important to keep track of the number of matches for a particular client or ACE? If so, you can use the op tional cnt (counter) feature in ACEs wh ere you want to know this information. This is especially useful if you want to verify that the sw itch is denying unwanted cli ent packets.
56 Enhancements Release M.10.02 Enhancements ■ Explicitly Denying Any IP T raffic: Enter ing a deny in ip from any to any ACE in an ACL denies all IP traffi c not previously pe rmitted or denied by that ACL. Any ACEs listed after that point have no effect.
57 Enhancements Release M.10.02 Enhancements Limits for RADIUS-Bas ed ACLs, Associated ACEs, and Counters T a ble 5 describes limi ts the switch supports in ACLs applied by a RADIUS server . Exceeding a li mit causes the related client authentication to fail.
58 Enhancements Release M.10.02 Enhancements Configuring an ACL in a RADIUS Server This section provides general gu idelines for conf iguring a RADIUS server to specify RADIUS-based ACLs. Also include d is an example con figuration for a FreeRADIUS server application.
