Whena network interface is bound to a channel, the channel parameters have precedence over the network interface parameters. (That is, the network interface parameters are ignored.) A network interface can be bound only to one channel.
When a network interface is bound to a channel, it drops its VLAN configuration. When network interfaces are bound to a channel, either manually or by LACP, they are removed from the VLANs that they originally belonged to and added to the default VLAN. However, you can bind the channel back to the old VLAN, or to a new one. For example, if you bind the network interfaces 1/2 and 1/3 to a VLAN with ID 2, and then bind them to a channel LA/1, the network interfaces are moved to the default VLAN, but you can bind them back to VLAN 2.
The Link Aggregation Control Protocol (LACP) enables network devices to exchange link aggregation information by exchanging LACP Data Units (LACPDUs). Therefore, you cannot enable LACP on network interfaces that are members of a channel that you created manually.
When using LACP to configure link aggregation, you use different commands and parameters for modifying link aggregation channels than you do for creating link aggregation channels. To remove a channel, you must disable LACP on all interfaces that are part of the channel.
The LACP system priority determines which peer device of an LACP LA channel can have control over the LA channel. This number is globally applied to all LACP channels on the appliance. The lower the value, the higher the priority.
For creating a link aggregation channel by using LACP, you need to enable LACP and specify the same LACP key on each interface that you want to be the part of the channel. For example, if you enable LACP and set the LACP Key to 3 on interfaces 1/1 and 1/2, a link aggregation channel LA/3 is created and interfaces 1/1 and 1/2 are automatically bound to it.
Link Redundancy using LACP channels enables the NetScaler to divide an LACP channel into logical subchannels, with one subchannel active and the others in standby mode. If the active subchannel fails to meet a minimum threshold of throughput, one of the standby subchannels becomes active and takes over.
A subchannel is created from links that are part of the LACP channel and are connected to a particular device. For example, for an LACP channel with four interfaces on a NetScaler, with two of the interfaces connected to device A and the other two connected to device B, the ADC creates two logical subchannels, one subchannel with two links to device A, and another subchannel with two links to device B.
To configure link redundancy for an LACP channel, set the lrMinThroughput parameter, which specifies the minimum throughput threshold (in Mbps) to be met by the active subchannel. Setting this parameter automatically creates the subchannels. When the maximum supported throughput of the active channel falls below the lrMinThroughput value, link failover occurs and a standby subchannel becomes active.
Say subchannel 1 is active, and its maximum supported throughput falls below the lrMinThroughput value (for example, one of its links fails, and the maximum supported throughput falls to 1000 Mbps). Subchannel 2 becomes active and takes over.
In a high availability (HA) configuration, if you want to configure throughput (throughput parameter) based HA failover and link redundancy (lrMinThroughput parameter) on an LACP channel, you must set the throughput parameter to a value less than or equal to that of the lrMinThroughput parameter.
Say subchannel 1 is active, and its maximum supported throughput falls below the lrMinThroughput value (for example, one of its links fails, and maximum supported throughput falls to 1000 Mbps). Subchannel 2 becomes active and takes over. HA failover does not occur, because the maximum supported throughput of the LACP channel is not less than the throughput parameter value:
So, I broke my smartphone's screen and in order to change it, one of the steps is to remove the battery. It happens that in the process of removing the battery I ripped off a bit of the wrap envolving it.
I already searched for a solution but didnt found it so here I am. The closest I found was people puncturing the batteries and they starting smoke but thats not the case. In my case it's really only a bit of the battery's cover.
Dr Franz Michel removed my scar tissue (Pterygium Growth). The surgery was on my left eye which had already had the procedure by a different doctor earlier. That doctor was horrible, but the experience with Dr Michel and his staff was great! He did a whole lot and he always took time to explain; never in a rush! He was more professional, and he is up to date with latest technologies and procedures. My recovery was quick and only with minor discomfort. If needed, I will definitely come back to see Dr. Michel and will recommend him wholeheartedly.
Dr. Michel speaks fluent Spanish and in serving the Latino community of Los Angeles County and Ventura County over the past 10 years he refined his Pterygium surgery technique to the point that they grow back less than 1% of the time. He has expanded to bring his fantastic track record to Los Angeles Pterygium in conjunction with Dr. J. Lin of Sherman Oaks.
A young man recently came to me with advanced Pterygium growths on his eyes. He was terrified of surgery and the look of fear in his face was striking. A close friend of his had the same Pterygium surgery years ago with another doctor and had a really hard time...
Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on

Dr Greenberg and Pottersman suggest the FeverPAIN score for helping a clinician judge the chances of a particular sore throat being associated with streptococci. A paper in the BMJ has suggested it is just as good as using current near patient testing (1).
This sort of conversation is always more useful in the context of a continuing relationship with a family doctor, rather than a transactional relationship which is inevitably occurring with the loss of personal General Practice.

Dr Rosen muses that she is a doctor not a supermarket. This is wholly correct. Doctors do not have the autonomy of supermarkets. Their practice is strictly regulated by didactic guidelines, which often do not have an exclusivley clinical origin. They are told what they can prescribe, when to prescribe to it and to whom. They told how to treat each condition and whom to treat. They are told the time frames in which they must see patients in an emergency and elective setting. Even with regard to life and death; they are told when a termination of pregnancy is lawful and when it is unlawful. How many of these decisions are made by doctors exercising professional judgment; as opposed to doctors being told how to exercise their professional judgment?
In spite of the worry about promoting antibiotic resistance, the commonest bacterial cause of acute sore throat, Streptococcus pyogenes (Group A haemolytic streptococcus) has never been reported to be resistant to penicillin. Giving penicillin to patients who need it (and are not penicillin allergic) will not increase antibiotic resistance in this organism. The situation is different for women with recurrent urinary tract infection. A significant number of these women will be suffering from the bladder pain syndrome. Repeated antibiotic courses for these patients may even make the symptoms worse and will certainly increase the antibiotic resistance problem. A formal research programme into this common and distressing condition is long overdue.

I sympathise with Rosen's concern on the conflict between professional judgement and customer satisfactions, and call for a solution. Unfortunately, it appears that our new generations of doctors are being taught to be good customer service providers more than responsible professionals.
I remember once in a communication workshop in medical school, I role-played a GP who faced a disgruntled patient complaining about my colleague's thick Asian accent. I was required to be sympathetic and apologetic to this patient, or else I could be accused of being unempathetic and defying the GMC Guidance on Good Medical Practice. In other communication workshops, I role-played a GP facing hostile pushback from an arrogant paramedic, a young doctor being undermined by a senior colleague, and a medical student being disrespected by an expert patient. In these role-plays, I was taught to be polite rather than standing up against the bullies.
These communication workshops are usually led by facilitators who had no medical training and side with the "customers." I appreciate how these workshops help physicians' negotiation and conflict-resolution skills; however, should these workshops also address the aggressive behaviour of instigators? These instigators probably need communication training more than physicians do.
