Simple troubleshooting of VLAN wireless Internet access switch faults

still pinged the gateway of the VLAN 172.25.6.210 on 6509 using a PC Connected to annett, the problem occurs. When ping with a packet, there is basically no latency, but packet loss occurs when ping with a large packet (close to 18024b, the maximum packet supported by Cisco). The problem must be found here. (5) re-check the configurations of annett, 6509, and NAT servers. We found a problem: Configure VLAN6 and VLAN7 on annett, and add the corresponding ports to VLAN: add VLAN 6 ports = 23 fram

value of the mantissa is not 0 o'clock, the most significant bit of the mantissa field should be 1, otherwise it is necessary to modify the order to move the decimal point around at the same time, so that it becomes a representation that meets this requirement, which is called the normalization of floating-point number.2.

and receiving, and provides standard interfaces to data link layer devices. The Physical Layer Chip is called PHY. The data link layer provides addressing mechanisms, data frame construction, data error check, transfer control, and standard data interfaces to the network layer. The data link layer chip in the ethernet card is called the MAC controller. Many NICs work together. The relationship between them is that the PCI bus is connected to the MAC bus, the MAC is connected to the PHY, And the

Double-end filter applied to grayscale and color image bilateral filtering for gray and color Images_ two-port filters

) Figure 5 Figure 5 (c) shows the result of five iterations of bilateral filtering of the "image in Figure 5 (a). While a single iteration produces a much cleaner image (Figure 5 (b)) than the original, and are probably sufficient for MO St Image processing needs, multiple iterations have the effect of flattening the colors in a image considerably, but with Out blurring edges. The resulting image has a much smaller-color map, and the effects of bilateral filtering-are to-when easier On a print

802.11 protocol inter-frame interval-sifs,difs,pifs,eifs

SIFS Short interframe Space (SIFS): SIFS is a fixed value in the 802.11 series WLAN, SIFS is the smallest inter-frame interval, so nodes with SIFS have the highest priority to access the wireless link. It is equal to the time it takes for the node to switch from the sending State to the receiving State and to decode it correctly, or the time it takes to transition from the receive State to the sending State, the packets that may be sent after the sifs expires include ACK, CTS frames, and the si

Mixed wireless networks often fall off the line Failure phenomenon Use the Linksys WPC54G network card and Linksys WRT54G AP to build a wireless LAN that uses IEEE 802.11G protocols and a few 802.11B network adapters. The line is often dropped when using wrt54g for 54mb/s connections. Fault analysis In theory, the IEEE 802.11g protocol is backward-compatible with the 802.11B protocol, and devices usi

Some of the parameters in Equation 1 are set to constants. First, the interval between packet reception and acknowledgement of message transmission is defined as 12 symbols in IEEE 802.15.4. In 802.15.4, a symbol is 4/240ms, so ta=48/250=0.192ms. Second, the IEEE802.15.4 receiver is able to reliably detect a confirmation message (a 4-byte long pilot code and a 1-byte long frame delimiter before the message is confirmed), so td=40/250 is required t

The earliest end-to-end virtualization feature was an Ethernet NIC and an Ethernet switch that supported the IEEE 802.1BR/Qbh standard. In this system, each Nic not only provides multiple virtual NICs, but also identifies each virtual Nic on the switch port by marking the VN-Tag of the Ethernet frame, additionally, you can flexibly divide the

What is the relationship between WI-FI and WLAN?

. ============================================Wi-Fi-FiWirelessFidelity, similar to Bluetooth, is a short-distance wireless technology used in offices and homes. This technology uses a 2-4 GHz band, which is currently not licensed as a wireless band. Currently, two standards are available: IEEE802.11a and IEEE802.11b. This technology has its own advantages, so it is favored by manufacturers. WI-FI is a non-profit organization held by a few American information companies with strong interest lever
