I have a WLC 5508 running 8.5.120 code.   I have wireless client who need to print from Apple devices to a HP M426 laserjet printer. So I set up the WLC for mDNS by doing the following: 1. Enabling mDNS snooping 2. Enabling global multicast and IGMP snooping 3. For the default-mdns-policy, I've enabled the _ipp._tcp.local. , _ipps._tcp.local. , _printer._tcp.local service names 4. Put both the clients and the printer on the same WLAN, and made sure the mDNS policy was enabled for the WLAN 5. Verified the clients could ping the HP printer    I see both the Brother and the HP printer in Controller-->Domain Name-->Summary  ,they are registered with the WLC with the correct MAC addresses and VLAN assignments.   In mDNS browser both devices show up, and the HP is using several service strings   But we can print the Brother printer, but not the HP. The HP will sometimes show up as an available Airprint printer but then vanish from the client. It never vanishes from the controller. I have tried updating the firmware, but it didn't help.   What could be the issue here? Did I forget to do something?  ... View more

I have two Nexus 9300 switches that are VPC'd together and connected to another two Nexus 7k switches upstream via VPC port-channels.   The first Nexus 9300 has a SVI interface that is peered-up via OSPF to an SVI interface on one of the 7ks. Those connections are configured as OSPF point-to-point. The second 9300 has a SVI with a different VLAN and IP network that is connected to the second 7k, and peered up via OSPF (point-to-point)   so imagine the Nexus 9300 stack with connections to two independent routers. One has a connection to the first router, and the second has a connection to the other.   If I do a show ip ospf neigh , I see the first 7k peered up to the first 9300. On the second 9300, I see the other 7k peered-up.   Both 9300s have the full routing table.   HOWEVER. Clients trying to connect to remote networks through the 9300s are getting 50% packet loss (frames are getting lost) if they come through a switch that is trunked to the 9300s. I haven't been able to determine why this is. I have the command layer3 peer-router on the VPC domain, along with vpc peer-gateway.    Is there something I did wrong here?      ... View more

Does Cisco have Visio stencils for SFP modules such as 10Gbs fiber, 100Gbs, etc?   I've looked all over the visio page on the cisco website, and found modules, but no SFPs.  ... View more

When configuring ports for private VLANs, do those ports already need to be in the VLAN per the command "switchport access vlan x"   example:   I have a primary private vlan 200 and a secondary isolated 201   vlan 200  private-vlan primary    vlan 201  private-vlan isolated   interface GigabitEthernet1/0/1  switchport  switchport mode private-vlan host   switchport private-vlan host-association 200 201   do I ALSO need    switchport access vlan 201 ...
