Hi All,   I am migrating a 5508 with Flex connect AP's at multiple sites to c9800cl.  Many AP's are connected to non-trunk ports with 'switchport access vlan X' and in the WLC those AP's/Flex groups have 'vlan support' unchecked, with no native vlan or vlan/mappings' set at all.  Basically all traffic ends up using the access port VLAN X at each site.   It seems I must enter values in the Policy/Flex profiles and haven't found a way to just uncheck 'vlan support'.  What is the easiest way to do this on the c9800?   Policy Profile - VLAN = ?   (do I have to set to VLAN X?) Flex Profile  - Native VLAN ID = ?  (do I also have to set to VLAN X) Flex Profile - VLAN tab =  (do I need to create VLAN X?)   Thanks ... View more

Hi,   I have an OSPF MTU question as we have a need to enable Jumbo Frames on our Nexus 7K FEX modules which will apply L2 MTU of 9216 to all FEX ports.    We have devices directly connected to the FEX (ASA's and ISR routers) peering OSPF with the Nexus 7K using an MTU of 1500 (SVI's and/or L3 FEX ports).  After we enable Jumbo frames the 'IP MTU' of the peering interfaces will still match at 1500, but the 'L2 MTU' of the ports will be mismatched.    In this scenario, does OSPF only require the 'IP MTU' to match to work properly?  Or could the L2 MTU mismatch cause issues?                 ...

Hi,   We have a multi cluster environment with LBM groups sharing CAC information between clusters. Desktop and Immersive class devices are split into separate video and immersive pools. ICT Trunks are in Shadow location with SIP profile mixed mode.   Within each cluster we have set the Service Parameter  'Video Call QOS Marking Policy' to 'Promote to immersive' to only deduct bandwidth from the immersive pool when calling from a Desktop device (eg, Jabber/8945) to an Immersive device (eg, VC unit or CMS).    However when calling 'between clusters' both Video and Immersive Pools are still being deducted at the Immersive regions value across all locations which is causing us multiple issues. Is this the expected behaviour? Is there any way we can avoid both pools being deducted between clusters?   Thanks ... View more

Hi, I have a L3 3850 Stack with IP Base license and just need to enable multicast routing between two VLAN's (SVIA and SVIB) on the switch. (no other L3 PIM devices/transit). The switch uses static routing for unicast traffic via another SVI to an ASA. (so no EIGRP or mcast 'uplink' interfaces) Do I need anything other than below to achieve above in my scenario?  (Cisco doc says for Pim Stub mode I also need to configure EIGRP stub and a physical uplink with PIM sparse dense on it, but unsure if this is only if need to receive mcast traffic from uplink?)   Thanks ip multicast routing int vlan A ip pim passive int vlan B ip pim passive ...

Hi,   I would like CUC to disconnect the call after playing the welcome message for a single users mailbox, so all callers hear the greeting but  cannot leave a voicemail. Can I do this for a single mailbox by setting the 'after greeting call action' to 'hang up' under users/edit/greetings for the 'standard' and 'internal' greetings for this user?  I don't want to affect any other mailboxes.   Thanks         ...

Hi,   Our client has a stack of four WS-C3750X-48PF-S switches running 122-58.SE2. CPU normally sits at 40% with Hulc Led Process using 20%.   Whenever the client uses Symantec Ghost to multicast images to a few pc's, the CPU goes to 60-65%.(low interrupts) Hulc Led Process increases from 20% to over 40% and we begin to see performance issues. (ip phones unregistering, voice quality issues)   The client has always used Ghost at other sites with switches other than the 3570X without issues. IGMP snooping is applied to all switches which should limit flooding.   Logs just show constant QOS trust state flapping of many ports which I"m guessing is the  phones resetting. %SWITCH_QOS_TB-5-TRUST_DEVICE_LOST %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED   sh proc cpu sorted | e 0.00 CPU utilization for five seconds: 62%/1%; one minute: 63%; five minutes: 64%  PID Runtime(ms)     Invoked      uSecs   5Sec   1Min   5Min TTY Process  169  2217217478  1221756240       1814 41.11% 40.29% 39.63%   0 Hulc LED Process   84  1172730971   710491500       1650  4.79%  4.51%  4.38%   0 RedEarth I2C dri   85  2347135764   473185300       4960  3.83%  3.79%  3.85%   0 RedEarth Tx Mana  129   900160394   102656819       8768  1.75%  1.98%  2.01%   0 hpm counter proc  232   147346287   303244735        485  1.27%  0.87%  0.79%   0 Spanning Tree       12    81720858   110076589        742  0.63%  0.29%  0.28%   0 ARP Input          181   182012633     9973080      18250  0.47%  0.46%  0.47%   0 HQM Stack Proces  259    92723044    74624511       1242  0.31%  0.15%  0.14%   0 XDR mcast          214    74069998   286681859        258  0.31%  0.12%  0.12%   0 IP Input           182   186201884    78177514       2381  0.31%  0.48%  0.48%   0 HRPC qos request  130    81857170   311631399        262  0.15%  0.20%  0.19%   0 HRPC pm-counters  107    19751840  1217497713         16  0.15%  0.15%  0.12%   0 HLFM address lea   86    41554684   334517325        124  0.15%  0.14%  0.13%   0 RedEarth Rx Mana  371    14803318  1052044058         14  0.15%  0.09%  0.10%   0 PIM Process        288    43349962     4914171       8821  0.15%  0.09%  0.10%   0 QoS stats proces  292    14095075   107528293        131  0.15%  0.09%  0.09%   0 Marvell wk-a Pow   43    36398731     8754807       4157  0.15%  0.08%  0.09%   0 Net Background     320    11719806  1527234091          7  0.15%  0.05%  0.05%   0 MMON MENG          279     5230640    99514899         52  0.15%  0.05%  0.02%   0 DHCPD Receive      I have a TAC case open but any suggestions would be appreciated.   Thanks       ...

Hi,   I am trying to implement CoPP on a 6500 and need some assistance. I wish to rotect the switch/network during any event such as virus outbreak, and retain remote access via telnet. I have created several classes for known traffic, and applied as transmit/transmit so I can fine tune the values. I am finding the below  challenges.   1. Many classes, despite averaging well below the CIR appear to 'burst' regularly into exceed/viotate. I have tried to increase  the 'CIR and bc/be' to higher values to get the exceeds down to zero. However they appear to keep bursting into exceed/violate.  I am unsure what do as I do not want to drop this traffic and cause more issues?   2. Despite classifying all known traffic, still 70-80% seems to be taken up by the 'class default'? Is this too high or ok? Do I need to more classification via spanning the control plane to wireshark?   I am worried I will cause more issues if important traffic is dropped? And that some traffic (such as spanning tree) cannot be classified out of the class default.   Just looking for some general guidance.   Thanks       ... View more

Hi guys, I am hitting a SIP  issue with CUCM 8.6.2 integrated with Exchange 2010 UM using TLS. About 10% of calls fail and just keep ringing when dialling the pilot. We found SIP is entering a race condition as it does not receive a DNS reply in time in between the Ringing and 200 OK received. TAC recommended to try and configure Exchange to delay the 200 OK if possible. Does anyone know if this can be done? ... View more

Hi all, We have a customer who recently upgraded from cucm 7.1(3) to 7.1(5). They all use 7962 em profiles,  (some have 1 line/1 speeddial, and others have 1 line/1 blf). They have always logged into 7942's and their speed dial or blf have always worked. After the upgrade to 7.1(5) users with 1 line/1 speed dial had their speed dial missing. Looking at em equivalency in the latest features and services guide 7.1(2), it says the default device profile for 7942's will be used in this scenario (which is 1 line/1blf). Sure enough if we change the default device profile to (1 line/1speed dial) the users with 1 line/1 speeddial profiles work. But it will break users with 1 line/1blf. I read the em equivalency section as it is behaving as normal now, and should not have worked before. But it apparently was. Is anyone aware of how this could have been working before, or any em equivalency changes between cucm 7.1(3) and 7.1(5) that could cause this? (I'm wondering if it was a bug that it was working before) ... View more
