Yes, it is working now. I connected Meraki to all ports of the router hoping at least one would and I got lucky. amusorf-wanrtr01#sh cdp nei Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone, D - Remote, C - CVTA, M - Two-port Mac Relay Device ID Local Intrfce Holdtme Capability Platform Port ID SEP20BBC0DD9DC8 Fas 0/1/1 176 H M IP Phone Port 1 SEP00B0E1EFE1B2 Fas 0/1/2 174 H M IP Phone Port 1 e0cbbc512cf6 Fas 0/1/0 166 R S Meraki MR Port 0 amusorf-wanrtr01#sh power inline PowerSupply SlotNum.

Hi Everyone, I have three cisco AIR-AP2702I-UXK9 model access points. None of them are responding to the console access. Same console cable works for 3750 switch and other routers but when connected to the access point they just dont respond. Just for your information. These access points are lightweight access points, now I need to convert them to autonomous access for that I need console access. Please advise.

Hello All, We are receiving complaints from remote users stating that they are experiencing slowness while accessing a particular File server at one of our service center (Costa Rica). Basically, their upload and download speed is constantly at 355 kbps. But they are not facing any slowness when they access network drives in a different data center. From this we assumed that issue is at our service center and continued to troubleshoot. Here is our findings. * From remote users machine, we issued continuous ping to the file server, we observed intermittent packet drops but there was no latency. *We initiated file copy from file server at service center to remote user machine. With help of Wireshark packet capture, we observed that there were a lot a TCP re-transmissions it means that the tcp packet is getting lost somewhere in the transit. *We checked the performance with the users at the service center, they reported no issues. Only remote users are experiencing slowness. *We opened a ticket with service center ISP for intermittent packet drops and ISP performed some tests confirmed that there is no issue at their end. *Packet drops is between 1%-2%. *We are seeing input errors on the WAN interface (Connection between WAN router and ISP) and LAN interface (Connection between WAN router and access switch) WMT-CR-SJ-RTR#sh int GigabitEthernet0/0 | i drops|error [WAN interface] Input queue: 0/75/0/54 (size/max/drops/flushes); Total output drops: 239 992 input errors, 0 CRC, 0 frame, 713158 overrun, 0 ignored 0 output errors, 0 collisions, 0 interface resets 0 unknown protocol drops WMT-CR-SJ-RTR#sh int GigabitEthernet0/1 | i drops|error [LAN interface] Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 552 input errors, 0 CRC, 0 frame, 276 overrun, 0 ignored 0 output errors, 0 collisions, 0 interface resets 11067 unknown protocol drops *Also, we are seeing high rate output drops on the interface where file server is connected to access switch.

Yes, we are using HSRP.

To be honest, I feel some configuration is missing on BDRLFSW02 or miss configuration that has caused this issue. Please see below. AM-US-SAT_6-DD-35-BDRLFSW01# sh hsrp group 599 brief *:IPv6 group #:group belongs to a bundle P indicates configured to preempt. | Interface Grp Prio P State Active addr Standby addr Group addr Vlan599 599 130 P Active local 172.28.219.4 172.28.219.1 (conf) AM-US-SAT_6-GD-35-BDRLFSW02# sh hsrp group 599 brief *:IPv6 group #:group belongs to a bundle P indicates configured to preempt. | Interface Grp Prio P State Active addr Standby addr Group addr Vlan599 599 100 P Listen 172.28.219.2 172.28.219.4 172.28.219.1 (conf) Above output says 172.28.219.2 is the active device and 172.28.219.4 is the stand by device. But when we did a SSH to 172.28.219.4, it is taking me to AM-US-SCF_01-0726-35-BDRLFSW01 which is at our disaster recovery datacenter. AM-US-SCF_01-0726-35-BDRLFSW01# sh hsrp group 599 brief *:IPv6 group #:group belongs to a bundle P indicates configured to preempt. | Interface Grp Prio P State Active addr Standby addr Group addr Vlan599 599 120 P Standby 172.28.219.2 local 172.28.219.254 (conf) HSRP is in stand by state for VLAN599 in our DR center. But, this should be like this, our requirement is when AM-US-SAT_6-DD-35-BDRLFSW01 fails AM-US-SAT_6-DD-35-BDRLFSW02 should take over the traffic not AM-US-SCF_01-0726-35-BDRLFSW01 becuase the group address are different at San Antonio DC and Scottsdale DR. Please advise.

The gateway for VLAN 599 is .1 in San Antonio but it is .254 in DR. This is by design. We are trying to understand why did the HSRP events occur on our Nexus Environment on April 7th? And what made VLAN 599 to become active at our DR and listen & standy state in our DR.

Could you please let me know if you need more outputs to investigate further? I am suspecting that there was a connectivity loss between the active and standy HSRP routers and both became active at the same time and might have resulted in the outage. Possibility?
