I have an autonomous Cisco AP1242 running on channel 11 (best channel avail) with only one client associated.
Signal Strength and Channel Utilization look good.
By design this client is constantly sending UDP/Multicast packets, so I had to disable IGMP Snooping on the AP. However, I have noticed data dropout and have been able to correlate it by running the command:
show interface dot11radio 0
Every-time I run the above command the Total Output Drops increases:
Dot11Radio0 is up, line protocol is up
Hardware is 802.11G Radio, address is 001c.b0eb.eb70 (bia 001c.b0eb.eb70)
MTU 1500 bytes, BW 54000 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters 00:37:46
Input queue: 0/1127/0/0 (size/max/drops/flushes); Total output drops: 3178
By design this client is constantly sending UDP/Multicast packets,
What type of volume you are talking about here, what is the data rate (bps & pps) of these multicast traffic flow takes ?. Keep in mind these radio may not have enough buffers to keep these (if you are sending high volume) & output packet drop is expected.
