in this method, you can shape the customer’s download speed and also upload speed as well . This is the best method I have ever experienced in cisco gear. ###Match the Vlan you want to shape. ##Once you will match the VLAN and then create a policy map and assign the bandwidth.
In the Cisco IOS on a Catalyst switch (not on a router), there’s an Interface Mode command called shape round-robin queue bandwidth. More specifically, the command is srr-queue bandwidth. This command has been around since IOS 12.2(25). For these examples, I’m using a Cisco Catalyst 2960 switch. Entering the command appended with a question mark will display the command options. Here’s… Read More »
The 16-bit subnet ID section of the IPv6 global unicast address can be used by an organization to create internal subnets. The subnet ID provides more than enough subnets and host support than will ever be needed in one subnet. For instance, the 16-bit section can: Create up to 65,536 /64 subnets. This does not include the possibility… Read More »
Suppose there is IP version 6 address 2001:1D11:220A::/48 assigned to an ISP with 16-bit subnet ID. The network administrators can subnet the IP version 6 address just counting /16-bit subnet ID in hexadecimal. This would allow the administrator to create 65,536 /64 subnet. The table below illustrates the subnetting procedure of IPv6 address. IPv6 Range. 2001:1D11:220A:0000::/48 2001:1D11:220A:0001::/48 2001:1D11:220A:0002::/48 2001:1D11:220A:0003::/48… Read More »
In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 – 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as… Read More »
An IPv6 address consists of 32 hexadecimal digits, in 8 sections of 4 digits each, separated by colons. It looks something like this: 1234:5678:90ab:cdef:1234:5678:90ab:cdef IPv6 addresses have several shortcuts that allow them to be compressed into smaller strings following certain rules. If there are any leading zeroes in a section, they may be left off. 0001:0001:0001:0001:0001:0001:0001:0001 could be written as 1:1:1:1:1:1:1:1. Any… Read More »
In IPv4 an address is split into two portions a network portion and a host portion.This was done initially using Address classes and later using subnet masking. In IPv6 we also have the same. The first step is to split the address into two parts. The address is split into 2 64 bit segments the first 64 bits… Read More »
There are several different ways to configure IPv6 and the exact method depends on the network design and architecture of the business model. Static Addressing Native and using IPv6 either on its own or in a dual-stack configuration alongside IPv4. DHCPv6 Address automatically obtained by DHCPv6 to an upstream server. Prefix delegation may also be used with DHCPv6… Read More »
In this blog, we will see the subnet size of IPv6, and also we will see some of the other information about IPv6 in this lesson. Let’s go ahead. IPv6 requires an IPv6-enabled network. IPv6 connectivity delivered directly by an ISP is ideal. Some ISPs deploy a dual stack configuration in which IPv4 and IPv6 are delivered simultaneously… Read More »
