Hello! Is there any official document that describes recommendations for moving DHCP server from Cisco platforms to hardware server depending on DHCP clients number? How many dhcp bindings or pool numbers can VSS Supervisor 720 handle without switching impact?

Hello everybody! There is a CUBE (Cisco 2821 witch IOS 12.4 (13)T) which is provided connections H323-to-SIP and vice versa between CCM 7.1 working on H323 and SIP softswitch of provider. As the CUBE is located between different subnets it has two different interfaces for CCM and SIP softswitch. There is no problem with voice unless putting an ACL on the inside interface of the CUBE (to the provider side) permitting traffic from SIP softswitch to the CUBE only. After putting the ACL there is no problem with signalling but RTP from provider is blocked. In the logs I see blocking traffic from the CUBE to CCM (from LAN interface to private address of CCM) on the interface with public addresses and therefore after adding neccessary string RTP is going through. The situation was the same with binding interfaces and without. Is that a normal behaviour? How can I avoid adding public addresses to the ACL on the Inernet interface? Here is the config of the CUBE. voice call send-alert ! voice service voip address-hiding allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 h323 emptycapability no h225 timeout keepalive sip ! ! ! voice class codec 1 codec preference 1 g711alaw codec preference 2 g711ulaw codec preference 3 g729r8 ! ! ! voice class h323 1 h225 timeout tcp establish 5 voice translation-rule 9 rule 1 /^9\([0-9]*\)/ /\1/ ! ! voice translation-profile Test translate called 9 interface GigabitEthernet0/0 description -- LAN Connection -- ip address 172.16.22.2 255.255.255.0 no ip redirects no ip proxy-arp duplex auto speed auto ! interface GigabitEthernet0/1 ip address x.x.x.x x.x.x.x ip access-group Test-in in no ip redirects no ip proxy-arp duplex auto speed auto no cdp enable ip route 0.0.0.0 0.0.0.0 172.16.22.1 ip route y.y.y.y y.y.y.y x.x.x.x.x ! ! no ip http server no ip http secure-server ! ip access-list extended Test-in permit ip host y.y.y.y host x.x.x.x permit ip host 172.16.22.2 host 172.16.22.3 permit ip host 172.16.22.2 host 172.16.22.4 deny ip any any log ! dial-peer voice 1 pots incoming called-number . direct-inward-dial ! dial-peer voice 20 voip answer-address .... voice-class codec 1 dtmf-relay rtp-nte no vad ! dial-peer voice 21 voip destination-pattern 5880201 voice-class codec 1 voice-class h323 1 session target ipv4:172.16.22.4 no vad ! dial-peer voice 22 voip preference 1 destination-pattern 5880202 voice-class codec 1 voice-class h323 1 session target ipv4:172.16.22.3 no vad ! dial-peer voice 2000 voip tone ringback alert-no-PI destination-pattern 311125425 session target ipv4:172.16.22.3 dtmf-relay rtp-nte codec g711alaw no vad ! dial-peer voice 2003 pots ! dial-peer voice 3002 voip description local calls translation-profile outgoing Test preference 1 max-conn 20 destination-pattern 9[12345679]...... translate-outgoing calling 9 max-redirects 10 session protocol sipv2 session target ipv4:y.y.y.y dtmf-relay rtp-nte codec g711alaw ! ! dial-peer voice 3005 voip description Long distance calls translation-profile outgoing Test preference 1 max-conn 20 destination-pattern 98[12345678]......... redirect ip2ip translate-outgoing calling 9 session protocol sipv2 session target ipv4:y.y.y.y dtmf-relay rtp-nte sip-notify h245-alphanumeric codec g711alaw no vad dial-peer voice 3007 voip description international calls translation-profile outgoing Test preference 1 max-conn 20 destination-pattern 9810.T redirect ip2ip translate-outgoing calling 9 max-redirects 10 session protocol sipv2 session target ipv4:y.y.y.y dtmf-relay rtp-nte sip-notify h245-alphanumeric codec g711alaw dial-peer voice 3010 voip description Emergency calls translation-profile outgoing Test preference 1 max-conn 20 destination-pattern 0. redirect ip2ip translate-outgoing calling 9 max-redirects 10 session protocol sipv2 session target ipv4:y.y.y.y dtmf-relay rtp-nte sip-notify h245-alphanumeric codec g711alaw ! ! dial-peer voice 25 voip session protocol sipv2 session target ipv4:y.y.y.y session transport udp incoming called-number 9T dtmf-relay rtp-nte codec g711alaw ! ! gateway timer receive-rtp 1200 ! sip-ua nat symmetric check-media-src sip-server ipv4:y.y.y.y no transport tcp

Thank you very much Giuseppe and Maria! According to cisco recommends I captured cpu profile but I can't interpret memory addresses as to understand what interrupts are being triggered so much ?

Hello everybody! The problem has appeared on 7206VXR after upgrading IOS from 12.4(11)T to 12.4(22)T2 - CPU utilization has increased into 2 or 3 times. This problem exists on 7206VXR with multilink PPP configuration on PA-MCX-8TE1 port adapter. It was supposed that this increasing of CPU utilization was caused by fast or process switching of this port adapter traffic and not cef switching. In the output of show cef interface it was: Serial5/0:0 is up (if_number 55) Corresponding hwidb fast_if_number 55 Corresponding hwidb firstsw->if_number 55 Internet Protocol processing disabled Interface is marked as point to point interface IPv4 packets switched to this interface are punted to the next slow path: PPP - unsupported interface Hardware idb is Serial5/0:0 Fast switching type 7, interface type 13 IP CEF switching enabled IP CEF switching turbo vector IP CEF turbo switching turbo vector IP prefix lookup IPv4 mtrie 8-8-8-8 optimized Input fast flags 0x0, Output fast flags 0x0 ifindex 22(22) Slot Slot unit 0 VC 0 Transmit limit accumulator 0x0 (0x0) IP MTU 0 Besides it was constant increasing number of packet of Unsupported CEF features.

Is it a bug of IOS or the problem in something else?

Hello everybody! There is a problem with ping and tracert to outside network when the L2TP client connects to the ASA. The client is in the inside network and via L2TP can access internal networks behind the ASA. It can access outside network too besides ping or tracert. Split tunneling in this case is achieved by adding static routes of inside networks on the L2TP client. At the same time the main gateway for L2TP client is VPN. There are diagram and configuration in the attachment. The one uncommon thing in this configuration is that L2TP goes through inside interface instead of outside. Does it matter? Is something wrong in my configuration?

Hello Guiseppe, Yes, I'm using netflow on my router and that's why I suspect the crash was caused by the bug CSCsm84257 or CSCsq75944. Besides in the list of affected version there was 12.4(11)T. Conditions of the bug CSCsx34297 are closed to mine too but I have the crash info not just unexpected reload of the router. The results of the output interpreter didn't help to make the problem clear. No bug exactly matches my errors.

Hello everybody! I have a problem with a 7200(NPE-G1) router with 12.4(11)T IOS. There was a system crash occured during normal use on a router. There was a message in logs: %SYS-2-WATCHDOG: Process aborted on watchdog timeout, process = Per-Second Jobs. I've found a bug CSCsm84257 in the resolved caveats of 12.4(11)T but in the description of the bug were only catalyst 6500 and 7600 listed. Is it possible that 7200 is affected by this bug too?

From the other side 12.2(33)SRC4 isn't listed in the affected versions of this bug. Is there any guarantee that this bug is fixed in 12.2(33)SRC4?
