  1. Flow control is a feature that allows the ASA's interface to send a message to the adjacent device (a switchport for example) in order to instruct it to stop sending traffic for a short amount of time. It does this when the FIFO reaches a certain high water mark
  2. ciscoasa(config-if)# flowcontrol send on 95 200 10000 If you have a traffic burst, dropped packets can occur if the burst exceeds the buffering capacity of the FIFO buffer on the NIC and the receive ring buffers

Flow control is a mechanism used to help manage the rate of data transfer between two devices. This is done to help prevent a source evice from overwhelming a destination device by sending more packets than the destination can handle. These scenarios can occur if a source device is faster than the destination device (CPU, RAM, NIC, etc) Symptom: N9K-FEX: 'flowcontrol send on' is set to po interface automatically after FEX replacement to other N2K box. At this time, 'flowcontrol send on' cannot be deleted by both 'no flowcontrol send on' and 'flowcontrol send off' commands. Moreover, FEX HIFs are not associated to this po interface with the following message I have a simple question. On routers, I can press Ctrl-C or almost any key to break out of a command output. But it doesn't work on ASA? So what would work on ASA? I read that pressing Crtl + Q would working but also failed . Thanks in advanc I was planning on setting up something like this on the ASA: interface Ethernet0/0. description WAN_Interface. nameif WAN. security-level 0. ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx. And add a default route to send all traffic out to the gateway via that interface. But, I am not sure how to setup the AT&T gateway to allow this The ASA doesn't seem to play nice with IPsec between a non-Cisco and Cisco product. My thinking is that if I can VLAN tag the incoming traffic, then I can let the VLAN tags get the IPsec tunnel traffic to where it needs to go at its ultimate endpoint where it will be de-encapsulated and read

It provides steps to turn off the Mailguard feature of the PIX or ASA firewall Flow-control defaults depend upon port speed. The defaults are as follows: Gigabit Ethernet ports default to off for receive and desired for send. Fast Ethernet ports default to off for receive and on for send

If one port experiences congestion and cannot receive any more traffic, it notifies the other port by sending a pause frame to stop sending until the condition clears Cisco ASA. Cisco ASA is one of the few event sources that can handle multiple types of logs on a single port because it hosts Firewall and VPN logs.

We will be creating a route based connection using IKEv2 and a VTI interface. We are also going to focus on how to achieve this using ASDM. Prerequisites. I am going to assume you are already using Azure and you already have a Virtual Network in. But after reading some documentation, FlowControl isn't an option. When a link between both switches gets congested the Catalyst 2960 would have to send a pause frame to the Catalyst 3750E and that's the problem.
